well if you emotionally ready for marriage i would assume you are "set"
You have had a small taste of what life will be with him being gone and you not able to talk every day, now make that many more months once he gets sea duty and that means that short of death you will not be able to contact him.
I would look at base housing first but that does depend on the area you will be stationed at.
My best advice would be be wary of everyone at first, not rude but more stand offish till you get to work out who is who, for instance sometimes the very first person to knock on your door to "welcome" you can end up being the local gossip who has worn out her welcome at every other military household. Also remember that HE is the one in not you............ he has the rank NOT you.
Make sure you can balance a check book and can stay on top of every bill along with saving a little bit each pay check, [yours and his] as when he gone for 5 + months at a time it will be you that has to do it all.
Enjoy and welcome to the navy life, remember treat it as an adventure and a GREAT opportunity for you both to really get set for the rest of your lives.
