.Map :: MoHAA Mapping

ive been working on my map for a while now and ive done some stuff. my map is a desert base in pakistan. ive scripted it so you can bash with almost all the wepons(ive got AA and i used SH's animations to make the ability to bash) ive gotten rid of the bozooka and replaced it with an auto sniper.

what i want in my match is for it to be a team match when you respawn instintly but i also want it to have an objective. theres 5 minutes on the clock and everyone respawns untill
A the control panel is destroyed
B the 5 minutes end

how would i do this?

Make it an objective map with level.dmrespawning = 1 (similar to the omaha beach objective map obj/obj_team3)

where do i type this in? in the entities? ive only been making dm's. can you give me a tut on how to make what i just said.
like, where to save it. what spawn points i need. and what do i need to put in my packscape? or just point me to a tut plz.
