Priests due to the fact that they have cloth armor.
Unfortunately no, Death Knights can not use shields...even when tanking.
In Cataclysm, Blizzard is making the Blood tree the tanking tree. However, currently (since Cataclysm is not out yet) all the trees can be used for tanking to an extent. Frost is one of the better ones at holding aggro. Blood tanks can self heal while tanking pretty good. Unholy is the least capable of the three.

Basically, just go down the protection tree. The protection tree is the tanking tree for warriors.
There is no 'BEST' class in wow. Each class has its strengths and weaknesses and can be overcome by another player who is better.
(My opinion) The best class would probably be the "evolved shamen" or the "necromancer". The worst class is "no class"
Absolutely not. There is not a "worst class ever" class. Each class has its own strengths and weaknesses.
That depends on personal play style, whether you like PvP, or PvE, and whether you like tanking or dps'ing in PvE. Arms is good for pVp, and PvE has fury for it's best dps spec, but the tank spec should only be picked if you like Tanking in PvE.
Worst thing to do I did that and my account got banned
A witch but that is not a class in WoW.

In the online game, World of Warcraft or WoW, there is one class that can use a spell called hex. That class is a shaman, characterized by their versatility, healer/dps status, and mail armor.
