Queries about the "Special Features"

I noticed that in the "mCenter" section there's this column title "ATS Special Features" and I'm guessing this is where you spend your accumulated points if you want to. I can see that most of the options here are pretty self-explainatory, but I was wondering if there's a detailed description of each option.

Also, I'd like to know, for example if I choose a "Custom mini-profile b/g colour," do I get to change the colour anytime from then on, or do I have to "purchase" it again everytime I want things changed?

P.S. If this question has been asked before, mods feel free to u2u me links to the right thread and delete this one.

Pretty much any of the things that say "Custom" in front of it, you have to pay each time you change them.
