Well. I'm now a 43 Drunken monk, so I can tell you my perspectives.

Tank
1. I personally went dex/str/con picking up int where I could.
2. I tank very well for short increments. Under certain circumstances I found I tank better than my Paladin (forgetting heals)
3. Hate stance (unfortunatly) is usually a must. Get Reed in the wind ASAP. Get a martial sword. Best suggestions I can give. It's really worth it to invest in an UR crafted martial sword.
4. I personally found I do more damage tanking than anything else. This is mostly thanks to instant-use no refresh counter attacks. The more evasion you have the better because you'll do more damage and have a better chance to use "Quivering palm" a counter attack that halves one enemies damage by 50% for 8 seconds.

As an asside. A combination of Qalian armor, mixed in with a few "of health" armor will allow you to heal quite well between the enemy missing you. Counter attacks help proc this. Mix in some Thestran Jewelry and you're golden.

Solo
1. Pretty well, not as good as a group, but I can solo even three dots without much trouble, and at the moment my gear is very poor (my headpiece is crafted level 31 =p)
2. I was still discovering monk as lower levels so I was pretty bad at it. I found once I got reed in the wind things started looking up. I am now dying to get the other drunken avoidance abilities. I wish they came sooner.
3. With good gear, 4 dots, I would say. This gets easier with errant strikes (essentially double damage as far as I can tell) and Fist of celerity.
4. Get your avoidance up. I found martial sword, reed in the wind and secret of flames work really well for damage (them attacking more means more counters which means more damage) Reed in the wind isn't only a defensive buff for us, but a DPS buff because of the counters.

I'm sure many will tell you Thestran is the way to go. And a few pieces are probably good. But I've found Qalian to be a real dream armor for myself. Oh, and with a disciple healer.. just droolerific. (hint, they turn the 14 point heal procs that you turned into 40 point heal procs into 90 point heal procs. With counter attacks or reed in the wind I can see my health go up during group fights )

This is what worked for me. I'd be very curious to see how others did it as well.
