Since your a photo school dropout, you prolly know more than others just getting into the game. The 15, 21, 40, 70 is a good sequence. I've got 21, 35, 40, 70 myself and one day will get the 15.
FWIW, I think the Macbook Airs max out at 4Gb RAM. If you're doing a lot of video, that's not enough. You may want to look at the Macbook Pros.
And have you considered a first person camera like the GoPro?
