I've composed for a wide variety of projects -- from movies (mainly my own) and cartoons to my friend's RPG -- and it's fun. It's actually the most fun thing I can think of, thinking how sound can match up with image...
I have no real advice as far as colleges go, since I've never went to college... I don't really have much advice period, since I've kinda just did what interested me and never paid attention to the "right" way to go about things... maybe there is no right way? I mean, unfortunately the world is stuffed with composers already. The usual advice is to "move to LA!" or "keep practicing". Both might be good advice. But eh.
Just dedicate yourself to something -- do you have a friend who makes videos or something and doesn't have a soundtrack? Practice soundtracking them. Rip scenes from movies and practice writing your own score. It's surprisingly fun. You'll quickly pick up on it and develop a passion for it I'm sure.
The best thing to have is FRUITY LOOPS (and any other good recording software with lots of plugins), possibly; since it can synthesize any sound ever made, it helps a lot. One technique I enjoy using in my films is to take a sound, like someone talking, cut it up, load it in Fruity Loops, and then play the sounds on the keyboard inside of FL Studio... then I'll slow what I just played down... so you'll often hear words repeat, but as notes in the background... I dunno why I mentioned that, except that experimenting is tops. You'll get noticed more for being unique.... and obviously the best advice is to just familiarize yourself with good music to begin with.
Why is Morricone so loved? Why is Goblin -- really, how does a disco prog band fit a horror score so well anyway? Knowing when to let your music sit back or stand up front is important, but you're already a talented musician so you already know this.
If you're wanting do tv work, listen to music on a show like Law and Order. Try to replay it. Study, study, study. Don't just study the good stuff -- study the bad, too. Why does that Miami Vice background music sound so fucking cheesy?
Great music to study would be any of Bernard Hermann or Badalementi's scores, I think. As far as video games, man... get the Killer7 soundtrack right away, this is one of the best soundtracks ever, and it perfectly encapsulates the (literally) schizophenric game. On the other side of the coin, get the soundtrack to ICO -- most of it is just like 30 second atmospheric sound clips, very minimal. Just like the game.
Also, I guess one thing is you probably will have to eventually commit to either being a game composer or a composer in the movie/tv industry (which means moving to LA, almost definitely). You're probably more likely to find a job as a game composer.
Here's everything you need to know about becoming a game composer:

one thing that's important to note is you may not have to move. But for movies and shit, you'll definitely have to move to LA, because you'll have to work very closely with the director.
I dunno, wish I could be more helpful.
