You'll be getting PCS orders pretty much the last 2 weeks of OCS. If you're going to move using the Navy it requires about a three week lead time minimum, so expect to have to report down yourself and then your wife after (unless you have family that can be there when they pack up your stuff).
You also have a choice in where you live. Double check when you get them, but you should have follow on orders to Whiting Field (since you have a dependant). If so, you can live in Pensecola, Milton, or inbetween. You will get the option to break your lease if you move more than 30 miles after API, so if you don't have much stuff you can minimize commute times by living in Pcola, then moving closer to Milton.
As for what job, it depends on what the wait time is like over there. You'll initially check into A-pool which is muster once a day and volunteer/get voluntold for jobs on occasion. Then you'll have IFS, which is pretty much tests for a couple weeks and civilian flying with Friday musters if you don't have a private pilots already. Then possibly A pool again. Then API, which is...fun. After that you'll have about a week or so (while still working) to move again.
Anyway, all that is dependant on your final select, getting through OCS, and getting through API. Lots of things can go wrong, but keep pushing. Good luck!
