Love Bare Minerals! When I started out, Sephora had a GREAT kit, maybe called Basics? Or "starter kit" (imagine that!). It came with two shades of foundation, mineral veil, warmth, lotion, a few brushes? Really, everything you need to start out. I think it was about $60, and if you belong to ebates you get a percentage back.
For starting out, I would get foundation, mineral veil, and one of their face colors. I don't like warmth for myself, but I am pasty pale and glow in the dark. Soft focus Glee works very well for me.
