If you don't already, record as often as you can--by yourself, with others, at home, in studios, at live venues. Also be aware that engineering is as much a service profession as a technical/musical one--people skills, patience, and integrity are very important.
Everything you learn about acoustics/electricity/electronics will set you apart from people who can push a mouse around in Pro Tools but don't understand fundamentals. Learn to align tape decks and troubleshoot/repair/re-cap older equipment and you could have a lucrative side gig as a tech.
A recording degree is no guarantee of getting a studio job but if you love recording and have a strong work ethic you should be able to make some good connections at school.
I highly recommend the
Tape Op and
Pro Sound Web forums.
As you note, now's the time to go for it, especially since you're young & free. Good luck!
