As a recently graduated college student who kept a reef tank throughout school, you seem to have the right idea. Take your time, buy good equipment slowly as you begin to need it and stay within your budget.
Only other general advice I can give for keeping a nano like this is to not overstock it. Like everyone else has said, parameters change much quicker in smaller tanks and having a heavy bioload will only make it harder to keep them stable.
Thanks for sharing your build and good luck!
As for stocking goes all I have really thought of is that I 100% want a pair of Black Ice Clowns and a diamond goby. As for corals I have no idea, just know that I'm keeping with softies and lps only.
