Where is FM School Located for HMFM 8404 Reservists located on the East Coast?

I've been Told either Camp LeJeune or Camp Johnson.....How long is C School? What type of rules and regulations should I expect? Is it as strict as Basic? Is it as free as Phase 3 in A school? What Should I expect ? Will I be able to leave base at all? At Night after training or on weekends? Will I have my cell phone and computer to stay in contact with my wife and child?
