I see a pattern of bad decisions here.
1) Being upside down on a car.
2) Having credit card debt.
3) Racking up massive debt and then choosing to abandon a good job.
4) Deciding to go to college just weeks AFTER the school year starts.
None of these are impossible to overcome, but you might want to rethink your monetary planning. Is going to college another bad monetary decision? I mean it seems like you already have a well-paying job. Or is this something that will really make your life better? If you can truely answer 'yes' to that last question, then go for it.
But I think you should wait a bit. Heck, you just missed the start of the school year. You might even be too late to get accepted into a college for the spring semester (it often takes many months). Thus, wait until next year to start. You can apply soon, but don't plan to go until summer/fall of 2007. The waiting time will allow you to do the important things:
1) Decide if going to college is really the right decision.
2) Pay off the credit card debt. There is no reason for you to have this.
3) Get the car loan mostly paid off, if not all paid off.
4) Sell the house. The housing market nationally has a glut of houses on the market. Thus, expect it to take longer to sell your house than in the recent past. Of course, your local situation may differ from the national situation.
