For AI programming, I'd suggest you Google for the term "finite state machine". Also do some googling for various other AI related terms. The more you learn, the more terms you will find for further googling.
For homing missiles, see my code at: http://www.blitzbasic.com/codearcs/codearcs.php?code=2258
You may also want to take a look at the various particle systems and other related code in the toolbox and code archives sections of this site (see the sub-menu on this page).
Also, I'd suggest you browse through the various examples that come with Blitz3D. There's probably some stuff in there that will help you out.
