Prior service marine joing the army?

I did 4 years in the marines now going into the army after being out for 7 months. I just wanted to know if anyone knew anything about when I leave meps I know that I get to pick where I wanna go but do I start getting paychecks starting at that date? And how do I get my uniforms and do I get to enroll my family in deers so that I can get put on a waitlist for base housing. I am also trying to get fort bragg do u think that is possible as a diesel mech? And are there any bonuses for prior service going into the army. Thanks
