I like the Desolace place. You can pickpocket the Nagas as well and they are mostly spaced out so you seldom get adds. I always carry around a few water-breathing potions so the underwater stuff is no big deal.
Another good underwater lockpicking place is Swamp of Sorrows in the lake surrounding the Sunken Temple. There is seldom anyone around picking locks and the respawn rate on the boxes isn't too bad.

or you could do what some prick of a rogue did on my server recently, and that is going throught the pirate camp in tanaris, pickpocketing every mob and not killing them...
LoL - I did that in Tyr's Hand while trying to get my lockpicking up to 300 so I could do Outland mobs. I really hate to pick and run but I didn't think I could handle the elites there at my level at the time. Once I picked the mobs though, I was stuck since there was no one else around to kill them so they'd respawn. It turns out I got better results picking the undead Trolls around that crypt in the southwest part of the zone and I could kill them to make them respawn and pick them over and over. :)
