I think you've chosen the wrong day to do this...Wednesday is patch day. I think a lot of people will be looking at getting Firelands daillies up and running and probably hitting Valor cap.
Unless your thinking of just sorting out 5 man parties and hitting Zanda hc's for valor cap, your trials may have been better if you done them on the day you think you'll raid, i.e Friday.
I don't like to put downers on your chances of creating a raid team as its just my opinion and meh i'm a warrior, so i don't know much. By the time i have finished doing everything required on main it'll be to late to offer my services on alts, but i am willing. It'll probably be my pally for healing, even though i havn't started healing yet on him in cata. But ask anyone they will tell you i'm a quick learner
