Sign up for airborne school. Its a trip. then do Air assault. Even if you don't make it through ranger school, which a lot don't, you'll still have some decoration. Helps come promotion time. You going in as an E-1? I hope not. But if you are don't fret... E2-E4 come quick. look for the green to gold program too.
Personally I would advise letting your asvab scores make your career choice. Think about your future. If you get out... Not a lot of civilian soldiers. You can get into the police, fire, or similar pretty easy... but If you score high enough you can get a job in the army... learn it and make a killing in the civilian world.

EDIT
I like 12M, 63B or now called 91B, all the 15's. 31B is OK. 40c is kinda a joke. 42's are the band geeks. 60's are in high demand in civy life. stay away from 79r if you can.
