Wanted to let you guys know that I've done a couple of LFR raids for the past days and they were actually not quite difficult at all. I seem to survive and heal rather easily.
Also, I've joined a raiding guild which currently does ToT normal, and we are at 10/12 at the moment. Really glad I could join particularly this one, because this way I don't dive in in the middle of something big (like SoO 11/14 HC or so), and get myself used to raiding.
Again, appreciate all your comments, thanks for the help!
