Well, since you actually want to be a professional, like any other kinds of business, there are many ways of going about this, not all of which require a "real" (true mathematical) bankroll.
You're young, if you were a little older and married what some people have done is gotten the support of their wives who have real jobs and can pay the life support bills if (when) you can't contribute. But that's off the table.
If you're actually going to be a full time professional, not only are you going to need a bankroll, you're going to need a nice little nest egg as well for several months living expenses. This is standard, most people who get laid off from their regular job is going to get some kind of severance, in addition to probably unemployment. You're going to have to fund all that yourself. What I would highly recommend doing is finishing your degree (while playing in the mean time obviously). Then you either have something to fall back on, or you can actually start in a job building up some nest egg while playing playing poker part time. Until you can make the switch over.
As Kevin said, you can look up online what the math equations are for risk of ruin bankroll requirements if you plug in the risk factors you desire.
As to tournament vs. cash, tournaments are a tough row to hoe. The variance is normally too high to be a mid level professional (the successful ones get lucky early on.) The higher level successful pros have books, coaching, online endorsments, etc etc to hold them over. Also, they stake pools of players. Which takes me to my point. Probably the best thing to do by going that route is to get a backer. For example, a friend of mine is (or was) backed by Eric Lindgren, who backs a pool of players. This reduces your payout of course, but smooths everything out to a manageable level. To get a backer, you'd have to prove yourself as a good player over the long term. And thus, getting back to having a job in the mean time.
For cash play, it's easier because the variance isn't as crazy (although still enough to drive you insane if you're not careful.) It's very difficult at low stakes to both
a) build up a bankroll and
b) pay for your living expenses
Getting a backer doesn't help with these, because even though it reduces your risk in higher stakes games, it reduces your income as well. Again, thus getting back to having a job while you build things up.
I personally am only a part time pro or semi-pro. Poker money is part of my income. I quit my corporate job to go into business for myself, which allows me another means of income, but at the same time the flexibility to work when I want (or more accurately, to not work when I don't want to - when there is a good poker game.) I do have backing, in fact one game that's very good is a little too high stakes for me, so I have a deal where I can't lose. All my losses are covered, and I give up half my winnings. (Of course I don't get the winnings until my losses are covered, but I can't ever be cash out of pocket.)
Perhaps you could find a similar work situation as mine by writing custom apps or doing web design consultation. Then you can pick your own hours.
