Dude I'm right up the road from you. Was stationed at Baumholder. Despite it's bad reputation, it's a great location for car enthusiasts. Only a two hour drive to Nurburgring, 2 hours to Frankfurt, 3 to Stuttgart, many many awesome driving roads around there (the short stretch from Baumholder to Kusel was always one of my favorites). I'd be more than happy to talk to you through PM or whatever and give you a knowledge dump.
As far as driving, start studying for the USAEUR license now so you can take the test and pass it as soon as you get there and don't have to wait on that after your car is there. Insurance is more expensive over there, but USAA treats us pretty good, and there are some Germany companies that weren't too bad to me and my friends as well.
