Sounds like you got the main things down. I would run regular until they are easy/farm mode. then use LFD for the H daily. You get 2 frost that way, I think you can play it until you finish the first dungeon. A week of that should tell you if you are ready to go all Herioc. The LFD will rate you so you don't start in Occulus (You hope) Takes time but you have several months until Cata.
