It is really rough trying to find a job while you are out of town. I used to be a truck driver, and I was home with about the same frequency. Potential employers don't really understand "I might be in town in two or three weeks for an interview". I ended up quitting and getting a crappy job just so I would be in town to look for a job and start school.
I don't regret it for a minute, but I had a little more freedom since I don't have a family. When you start school, go to a community college. If you know what you want to major in, make sure you know there transfer policy really well...you don't want to take classes that won't transfer or count for your major. Also, even if you have a major picked out, take classes that count for multiple majors. Mostly do all of the general ed stuff. Most people change majors a few times before settling on one, so you don't want to put all of your time in to classes that you may end up not using. General ed should count for all majors.
I really don't see any value taking 100 or 200 level courses at the University; they are the same, just more expensive. Financial aid only counts for 1 school at a time, so pick one, and take full time credits at that one.
I changed majors twice. I started at University of Phoenix since I could do it after work. It is hugely overpriced, and I wouldn't recommend it to anyone. I took 7 classes there, and spent $8,000. Only one of them ended up transferring, so I basically paid $8000 for English 101. What a waste. I was majoring in Psychology there since it sounded like the most interesting one they had. When I got to a real school, I chose engineering. I started in civil, then switched to computer engineering after deciding civil was about the most boring thing in the world.
Those 3 decisions ended up adding a year to school. I would be done now without the wasted classes, but I still have this semester, and one more class next semester to finish. Just trying to save a little time for you if I can.
I go to school with a kid your age (yeah, I am almost 40, so I usually call them kids

), and he proves all of the time that you can go to school, work, and raise a family. It won't be a fun 4 - 6 years for you, but it is definitely doable.
More on topic, I sold a bunch of my games a while back because I needed the money. It really wasn't worth it. If you have to sell fast, you will usually not sell them for enough to matter.
Good Luck!
