nothing beats the 4 yr degree...I just got mine...BA in Liberal Arts. I'm going back next year (working for my school too!) for my Masters in Science in Leadership and Management, so I'll have yet another edge. the more schooling you have, the more it shows employers you care for your advancement. you may ask an employer in your area (such as the non-glamorous Walmart or RadioShack) if they would pay for your schooling, while you work for them. 3 years working for a business, and they will pay your college expenses...best to check around for the better deals. then again, for the most technical of all education, try the military. the Navy is reportedly on par with the Army in money spent training computer technicians, but my data may be slightly outdated. try the services for 3-5 years...not only will you be trained, but you'll have a lifetime of medical coverage, insurance, and a great resume-booster!
education in form of schooling outweighs a certification course you may pass online, any day. remember that your peers may not be able to afford schooling, so they will get all the certificates possible, without the degree. get your degree, no matter how much it hurts.
imo, though my parents paid for my schooling (in full), I would have put myself through school if I needed to. I was prepared to ask the Navy to help, but my mom convinced me to stay a civilian for a few years more.

one more thing...taking a year off from high school is fun, but you may lose momentum, and find that college is harder than it would have been right out of high school.
