You may want to consider getting your LVN/LPN first. It's a one-year program and after licensure you can go directly into the second year of nursing school and a year later have your RN. It would still take you the same amount of time to get your RN, but halfway through you could start working as an LVN if you needed cash. As a registry LVN you can set your own schedule, so you would still have time for school. Starting pay for LVNs in California is $21/hr.
Going the LVN route first also lets you experience what nursing is all about. If you find you don't like it, you have only invested one year into it instead of the two years required for an RN. That means you would also only use one year of your GI Bill benefits. Nursing isn't for everyone. You will be dealing with shit, piss, blood, and vomit on a daily basis. On the other hand it has great job security.
You may want to also consider allied health professions. Radiology techs make a median income of $56K. Respiratory therapists can make as much as $60K. Physical therapists are in demand and can make as much as $80K (these salaries are all in California; Las Vegas may vary, of course). These are all much more pleasant jobs than nursing.
P.S. As for being a male nurse (and black) you will find yourself in great demand in nursing, as hospitals are interested in "diversity" of employees.
