[T.I.]

I am/you are tired of making many damn topics for new and new subjects about scripting, so I will make one which I will ask whatever I need.
I want to do these things:
When you join a gang, at in the gang house must be a room where you can take some guns. Could someone script it for me/help me?
I mean like a Police /duty.
When you join a gang, at the spawn point must be a "?" object and you have to type "/guns" and it will give you to choose what gun to choose from these:
-Deagle
-Shotgun
-Baseball Bat

Could you help me?
