I'm headed to Korea with the 2nd ID. I wanna be a line medic. Most people who get a specialty get it before they enlist. Otherwise, you have to have been a 68W for at least 12 months. I know quite a few people who joined with a M6 Identifier. A LPN get's no bonuses, but a Nationaly Registered EMT can fast track past the first 8 or so weeks of training since it's EMT-B training. Alot of people come in with rank for college credit or completeing task lists for recruiters, such as learning the general orders, passing a APFT, learning land nav, etc. Incentives are all handled by recruiters, I'd just make sure everythings on paper, especially M6. Also, there are large bonuses to be a 68W. Most get $20,000 for 6 years I think. But since my original entry MOS was switched to a 68W I got a shorter contract and no cash bonus.
