The paw can be worn in either hand. Also, it can be sold for several thousand plat.
The quest can definitively be done by a 34 druid. I would hesitate to recommend a lower level, mostly because of the Guk part of the quest. Teaming up would help here, though doing it alone is possible at 34. This is written from the perspective of a druid, though most of it would apply also to a cleric or shaman.
Be aware that you will become KOS to the frogloks if you aren't already.

Overview of the quest

1. Get the severed paw from Vin Moltor in the Qeynos Catacombs.
2. Get the platinum ring, and possibly the copper and/or gold one, from Gynok Moltor in Befallen.
3. Get the Guk Bracket Mildew (for copper), the Degenerated Guk Weed (for gold), and possibly the Faerix Spores (for silver) from the Fungus Mutant in Upper Guk.
4. Turn the items from Guk into Melixis on Kerra Island, and obtain the corresponding rings from her.
5. Get the silver ring from the razorgill pool in Blackburrow.
6. Combine the four rings in the severed paw, and enjoy your brand new Paw of Opolla.

The quest does not have to be done in this exact order, though I would recommend doing the Befallen part before the Guk part, since Gynok will sometimes drop the copper or gold ring. Also if you wait until you have done the Guk part, you may be able to skip the Blackburrow part, though this isn't a big issue.

Dispelling some common myths

Myth #1: Mitty drops most of the rings. This was changed with the revamp of Kerra. You now need to get the listed items from Guk and give them to Melixis.

Myth #2: Gynok is an 8 hour spawn. Gynok is a random spawn on a fifteen minute timer. He has been known to take more than fifteen hours to spawn. He has also been known to respawn in much less than eight hours.

Myth #3: Gynok only drops the platinum ring. Gynok sometimes drops the copper ring. He might also drop the gold one.

Myth #4: The rats are placeholders for Gynok. Gynok always spawns at the same place. The only rats that are placeholders are the ones that spawn in this spot.

Myth #5: I need the Faerix Spores for the silver ring. The silver ring can be obtained faster and more easily in Blackburrow. If you just happen to get the spores though you might as well use them.

The severed paw from Qeynos

Go to Qeynos. When facing the gate, the entrance to the catacombs is to your left, around the corner, behind some vines on the wall. Actually there are more entrances, but this is the one you want. Behind the wall is a small room with a well. Jump into the well and swim down. You will zone into the Qeynos Catacombs.
Now look for Vin Moltor. He spawns somewhere close to the entrance and wanders around. He looks just like the beggars. If your baking skill is very high, you can trade him for the paw, else just kill him and loot. The severed paw looks like a paw (duh), and is actually a 4 slot container.
Don't go too deep into the catacombs. There is a necromancer guild here, and there is some nasty stuff you can run into, such as spectres and a rotting sentry. The sentry can kill a mid 30's in a matter of seconds.

Gynok Moltor in Befallen

Gynok is a mummy. He spawns just inside the zone. His placeholders include various skeletons, rats, and ghouls. They will immediately start walking into the dungeon, going right through the first locked door. Go stand where you can see them come. Just kill the placeholders. If you can cope with Gynok, you can swat his placeholders like flies.
When Gynok spawns, kill him and loot. If you get the platinum ring, you are done in Befallen. Sometimes he drops a different ring. This is both a blessing and a curse. A blessing because now you don't have to get the component for this ring from Guk. A curse because you now have to camp Gynok all over again for the platinum ring. Based on his fighting, Gynok would seem to be somewhere in the middle 20's.

The Fungus Mutant in Upper Guk

This is the hardest part of the quest. The fungus mutant spawns in the mushroom farm. Consult one of the maps on the internet for how to get there. Hint: go via the pit with the ladder.
The mutant spawns in the corner to the right of the ladder (when standing in the room, facing the ladder). He has no placeholders. He drops an item about half of the time. The items you are looking for:

• the Guk Bracket Mildew (common)
• the Degenerated Guk Weed (rare)
• the Faerix Spores (ultra rare)

You don't need the spores, but if they drop, just keep them.
The room also spawns fungus drones, sometimes a fungus soldier, and occasionally a fungus breeder (who looks just like the mutant). Also an ancient fungus might spawn. Some of these may attack you. They will wander around part of the time.
The fungus drones cast low level druid spells. They will cast minor healing on whomever you are attacking. The mutant casts the same spells, and in addition a Clockwork Poison spell. This spell will make you spin really fast for a few seconds, during which you cannot cast. Though supposedly a poison spell, there is some indication that this spell may be magic based.
Another danger to watch for are the frogloks. Sometimes one will stand at the top of the ladder for a while. And once in a while a froglok will cross the room. The frogs will attack you when they see you fight, even if they are green to you.
When camping this room, it helps to keep the room clear, killing the fungi as they spawn. Keep your magic, poison, and fire resistances up. Be sure to snare what you fight, the fungi will run and bring back (frog) friends. Hide (make sure it worked) or go invis before you sit down to meditate.
One final note. The fungi belong to the same faction as the frogloks. It takes only one kill to become KOS to them. So don't just assume those frogs are still dubious.

Melixis on Kerra Island

Melixis sells alchemy ingredients in a hut to the left of the palace. Give her the items you retrieved from the mutant in Guk, and she will give you the corresponding rings in return. And that is all there is to it.

The silver ring from Blackburrow

If you don't have the silver ring yet, go to Blackburrow. Cast levitate and enduring breath on yourself and just jump into the pit. The ring is on the bottom of the pool. It looks like a little bag (like when you throw your fishing grubs on the ground). When you pick it up, it reappears after a game day, so if it is not there, come back for it later. Now just gate or teleport out.
You will be attacked by razorgills, but they are merely an annoyance. Just ignore them, get the ring, and leave.
