First of all congrats to all those friends who have been selected in FGEI (C/G), as far as this job is concerned, I would request them to visit your nearest school & meet teachers to have a clear idea of FGEI. It can't be discussed here thoroughly. Every deptt has pros & cons. Anyhow, u must be crystal clear that u r joining Education deptt, & it is very prestigious & respectable profession but very different from executive posts. Although with the passage of time normally teachers are adjusted to nearest stations but U must be ready to serve anywhere in FGEI throughout Pakistan & I don't think that there is any govt school in all govt deptts (sorry if there are some special cases) with residential colonies within Pakistan but they make some local arrangements like reserving or building some rooms or hostel for bachelors & arranging some family quarters.
Wish u all good luck & the choice still rests with u
