For what it's worth:
Nothing can replace a college education. Most "career" jobs in the US require a college degree, and while it is certainly possible to climb the corporate ladder without a degree, you'll need a healthy dose of luck to do it that way.
Get a college degree, if only for the simple fact that most companies won't even consider hiring you without one. "The more you learn, the more you earn" is not just a hollow slogan - just look at the numbers straight from the horse's mouth: http://nces.ed.gov/fastfacts/display.asp?id=77 : $23,500 with a high school diploma or GED, $39,500 with at least a Bachelor's (and that's the median, not an average). With a difference of $16,000 per year, I'd say it's pretty obvious you shouldn't worry too much about racking up student loans...
Also: have you considered online degrees? Some colleges offer fully accredited online degrees that you can complete while you're working, and you wouldn't be restricted to your geographical area. The "Tech Institute for Computer Networking Systems" from your first post makes me hope you're not signing up for some Associate's degree that isn't even accredited. Get a bachelor's (and preferably top it off with a master's) from a decent accredited school, and all doors will open for you.
