If you really want to get into some of the crazy stuff that they do in F1, here's some good sources of information from one of the best (IMO) armchair analysts in the sport, Craig Scarborough.
On the basic level for those getting into the sport (like yourself) he has some writeups on this site: [Invalid or Expired Link Removed] explaining all of the general characteristics in relatively laymans terms.
And when it gets to the more advanced stuff, there's his proper blog
www.scarbsf1.com which has incredibly detailed analysis of race-to-race aero changes, as well as a yearly rules analysis and other fun information.
Enjoy!
