Which zone should i start leveling at?

[Yeska]

1 Im going to make a shadowknight. Im not sure if i want to ma make it an oggre, an erudite or a dark elf. Anti stun vs mana pool etc. what should i choose?

2 i like to group, where should i start leveling? Pop and go to antonica or faydwer? wait until lvl 5?

3 I dont remember very well how it worked in classic but:

Warriors>sk in dps
Sk>paladin in dps
SK>all in aggro unles the warrior have haste and procs

is that right?

And sorry about my crappy english =)
