Military Wedding

I am 18 years old and I have been dating this guy for 3 years and he just asked me to marry him. Even though i told him yes i am a total wreck about the whole thing b/c i am completely clueless as to what i should do first! we picked a date out (june 14, 2006) and we have established that b/c he is in the airforce that it will be a military wedding. Other than that though i dont know what to do first or anything. On top of that though i am clueless about the rules and stuff about military weddings. I would appreciate any help i could get! thanks!!!!! *heather*
