As said before, Listen to your enlisted folks, they will know alot more (about the specific job) than you at first, and will respect you alot more if you come more asking questions than barking (mis-)directions.
Don't get bogged down by the fact as a 2nd Lt. you have to salute EVERYBODY... 2 yrs and you'll be a blue bar. No worries.
If you don't mind me asking, why ROTC, did you apply(or consider) the academy? Prior enlisted at all?
and of course... What was your Signing bonus? Or have you not gotten it yet?
(Fellow AF so don't mind the squids lol.)
