Trouble in Terrorist Town - Player Collisions and Custom Ammo

[Doomblade3890]

OK so I'm making a map for the Trouble in Terrorist Town gamemode.
I'm nearly done with the map, but I'm still trying to figure some things out.

First off, I'm trying to figure out a way to disable player collisions when a [B]trigger_multiple[/B] entity is triggered by the player.
The method I'm currently testing out is using a [B]logic_collision_pair[/B] entity. Right now I'm testing out the collisions with a citizen NPC (named testNPC).

So here's the problem:

When I test the map, I run into the testNPC and I am unable to run through it. I have activated the [B]trigger_multiple[/B] entity, so the [B]logic_collision_pair[/B] entity should have activated. Also I have tried this with the "Start with collisions disabled" field set to both [I]yes [/I]and [I]no[/I], both of which have failed to yield results. I have also tried using both the [B]!player [/B]and [B]player[/B] keywords as listed in the [URL="https://developer.valvesoftware.com/wiki/Targetname"]VALVE Developer Wiki[/URL], but have been unable to get the collisions to disable.

I'm trying to get [B]all[/B] players to no-collide with each other so they don't get stuck in a teleport.

The second problem I'm having is with some TTT weapons. In the map, I want certain spawned guns to have a starting ammo value. I've noticed in CS:S maps like in Jailbreak maps some spawned weapons will have a custom ammo value to them. I'm wondering if this can be done in HAMMER for the TTT maps, or if there is something else that needs to be done to accomplish this?
