Help!! Making custom map in SC2. Units?!?!?

[SaltyPuddles]

Hola everyone. I have a couple questions for the SC2 modding and custom community. Im trying to make a custom game called a "maze", such as the ones seen in Warcraft 3: The Frozen Throne. This game will require moddification of units, which is my first question. Where is a screen/ how can i modify statistics of a unit such as movement speed or no attack? Second it will need units to have a kill region around them, to where if a certain unit (marine) touches said units it will die. Is this possible in this editor and if so where? Thirdly i want to have zones for the marines (the units that the players cntrl) that when they step into this area it respawns everyones "hero"(marine). no clue how to do this either. Help would be very appreciated and i will be sure to list you on the title screen of the game if/when it is done :P. Thanks
