I think it is really hard to give advice without more information about what you're goals and interests are. I LOVE to get dirty, so being an Equipment Operator in the Seabees is the perfect job for me. Some people can't take the heat/cold, playing with belt fed granade launchers or getting dirt under thier nails... ect so being a Personelman is a better life for them.
I'll try to clairify some of the stuff I've seen posted. From the beginning...
As far as recruiters, some are good and some are not. If the guy is talking everything way up, like there are nothing but sunny days and blue skys, walk away 'cause he's BSing you more than usual. If they try to preassure you into anything, walk away. You have plenty of time to make your own (informed) decisions. Everyhing goes with a grain of salt and gets double checked. However, Most recruiters are honest (more or less) people who really want to help you. Become friends with the recruiter because he will have the latest training on the programs that are available.
The Army DOES have a Warrant Officer Program for Helocopter pilots. They do NOT require a degree or prior service. I believe all other Warrant programs require time as enlisted ( I may be wrong). I am not sure about the medical requirments.
If you can afford to get into some kind of officer program it may or may not be the life you are looking for. Please remember to listen and take care of your enlisted people if you do get to go officer. They know what's going on in you're command. You won't.
Don't make generalizations- The Navy dosn't always go on ships, The Marines are not always in the field and sometimes the Airforce gets dirty. It will depend a lot on your job and your command.
Bruce is right about changing your career field. While you may get good training in a civilian career field, it also needs to be something you like. They tried like crazy to get me to go into nuclear power, which makes good money, but would not be the life for me in or out of the military. Also, think about how you would like to use any training after you get out. An aircraft mechanic would be pretty good if you move to a major city (that has aircraft), but next to useless if you decide to go out into the country and 'get away from it all'. On the other hand a tank mechanic could prolly find a job at TACOM (where they build tanks)
Some jobs sound good on paper but don't produce on the outside. I don't know about SinistrV6's 'site developer' training, (Don't they go to Fort Lenard Wood?) but it sounds like an 'Engineering Aide' in the 'bees. I have worked with them and they are VERY good at what they do. Even so, many companies will not hire CAD people without a degree. That piece of paper means much more than real experience to some people. (ask me how I know)
Be prepared for a dissapointment. Depending on your command you may work gravy hours, or you may work every waking moment. It's a gamble. Since you are used to working long hours, it's prolly a good bet that the Airforce will be easier than your life now. Unless you go to some slab of concrete in the middle of the sandbox. It's also a good bet that you will not make as much money.
Finally, Use the reserves. You can use them in a couple of different ways. First off, if you find a job you like, see if there is a Reserve Center around with that kind of unit. You can go out and talk to people who have 'been there, done that'. Occasionally you will get to go to a drill and actually see this stuff. You kinda have to make them think you want to join the reserves to get in real good with them

*HINT* Try to find a lower (not the lowest) ranking guy and talk to him alone. As we go up in rank our jobs get easier and we tend to forget all the BS we had to put up with. Another possibility is to actually join the reserves for a while and see how you like it. I had a 3rd class a few months ago who had been in a program, I think it was try the Guard for a year. He didn't care for the job so well, so after doing his year he left.
However you decide to go, Good luck with it and be safe. Don't do anything stupid and try to have fun. Oh, and get a good digital camera. If you deploy anywhere good the film development cost will eat you alive. My last count was 16,535 pics since the beginning of my most recent recall (03MAR03) That's about 8.4 GIGABYTE of pictures, so add a good size hard drive too
