Need help with slightly different mind control

Alright, so I've seen the code to have a player switch teams by chance on attack. Okay, that's nothing new. I want to get code set up to where the player would have the mind control set to an ability and be able to change a person to their team if the person's level was less than theirs and then it would initiate a cooldown AND give the player exp for a kill. I play regularly on a server that uses this as an ability for Dark Archon (those starcraft fans out there will recognize this) and i was wanting to make myself a nice Jedi race with the same ability as a Jedi Mind Trick kinda thing, ya know? Few questions to get everyone started on helping me and then any bit of code you could me out with would be great.

1.) Since this is a use ability, would I specify it as player_spawn or player_attacker?

2.) How do i set up usable abilities in script? More specifically, what are codes to setup cool downs and whatnot?

3.)After all this is said and done, how would I code in the extra experience?

4.) And how would I do coding to check what the level for the other player is and run it against the level of the player using the ability? I know it's something along the lines of (but not in code form): store player a's level, store player b's level, if b <= a, then run alias for mind control script. But I don't quite no how to enter those variables.

Anything else you would like to add would be greatly appreciated. Here's the original code for the on chance with attack ability. Any tweaking and reposting of code you could do for me would be good too.

Code:

"skill3_setting" "es_xsetinfo wcs_chance 3|es_xsetinfo wcs_chance 4|es_xsetinfo wcs_chance 5|es_xsetinfo wcs_chance 6|es_xsetinfo wcs_chance 7"

"skill3_sfx" "0"

Really appreciate the so far with my ideas. Hope you guys can me on this one too
