Gnoll, Gnome, Drow, Githyanki (spelling??), Shifters (two kinds), Dopelgangers, and Warforged.
Off the top of my head Warforged looked like:
6' - 6'6"
+2 STR +2 CON
They don't eat, drink or breath but it doesn't negate any effect. ( ie gas cloud effects would still affect them)
+2 to saving throws to end effects
+2 endurance skill
extended rest is shortened to 4 hours
Racial ability is called Warforged resolve. I believe its an encounter power
Activated when the character becomes bloodied.
3+1/2 lvl temporary hitpoints
The racial ability for PC warforged did not match the NPC verison. There is a 4th lvl NPC that gains 14 temp hitpoints when bloodied, and a lvl 6 one that gains 18. Which would seem like 4+2*lvl to me. At 6th level a PC would gain 6 hp.
Thats all I remember for now.
