What should I try to do while still in college?
gm: Do EVERYTHING you can that will not be economically feasible (travel for a month or three) or even possible (spend a summer at Cambridge University in England).  You will live to regret not doign these things when, after you get a job, you get two measly weeks of vacation per year.Use it all up: take extra classes, join a club, make a friend from another race, etc...
