I work for a Medical insurance company and the one thing that sticks out most is that not enough people know data bases!! We use a lot of MS SQL for the heavy duty stuff and MS Access (possible the worst program on the planet in my book) for the lighter stuff to filter through lots and lots of data. Out of 60+ people on my floor there are 2 people that really know what they are doing with data bases and the rest of us are pawns in a chess game!! LOL The power of a little data base knowledge is amazing and can get you some good money!!
Also believe it or not doing web pages is a pretty good thing to learn too. I have no formal training at all and i got a couple side jobs running a couple online stores. Through these jobs I have a couple more in the works just through referrals.
My advice is to figure out what you like doing in the IT world and start messing with whatever you decide on. I myself like HTML, Photoshop, PHP, Javascript, OScommerce, Wordpress, and Drupal. I have never taken a class in any of these and can use them pretty well. Also if you have friends that are good at something get them to show you a little here and there. Its always good to have a different perspective.
Good Luck
