No grenades in spawn is a brush entity. Trigger_ff_script with the name "no_grens" you can also use "spawn_protection" which will block grenades, infection, and prevent building. Make sure to include base_teamplay in your lua.

For spawn killing doors you can do that by using a trigger_hurt and lua that detects the team.

Here is some lua from aardvark for an example. Good luck.

	local player = CastToPlayer( activator )
	if player then
		if player:GetTeamId() == self.team then
			return EVENT_ALLOWED

	return EVENT_DISALLOWED
end

	local player = CastToPlayer( activator )
