I was basically hoping to work my way up the old raid mobs as I level up... I've been looking for a list but haven't been able to find one yet

Also I will be 2-boxing and can't decide which classes to take... I was thinking mage/shaman but wasn't sure if that was good for what I am looking to do.
basically what I am wondering is this:
A) Is what I want to do even possible to do by yourself?
B) is there a website that has a list of old raid bosses :p
C) Is it that hard to get back into the swing of things? I really don't remember how to play at all... which is another reason I want to start from scratch (minus plat of course

D) do people camp these bosses? I would hate to not be able to kill them because they are killed right as they spawn ya know? :p
This post was supposed to be longer with more questions and such but I get out of work in 3 mins lol
Oh and I know this might not be the best place to post this but I have been reading your forums for a few days and decided to register and post here because the people seem to be nice :p Sorry if its an annoying post ;o
