Need help with a couple of triggers!

[Azndragon]

HELP PLEASE!!

I need help with periodic unit spawning, not just that I know how to make units spawn every x seconds and everything, I know all the basics and a little bit of advanced things HOWEVER, I need help with this:

•How can I make units spawn in a region for the player who owns a certain building?

•Giving a building to player who is attacking it and then healing the building to 100% when it's health is under 10%

Ok, here is how I want it to work..
Yellows village spawns 10 nord recruits (periodic spawn in region trigger) and red attacks, red defeats yellow's recruits and brings the village's health down to 9%, the village is then given to red AND the village now spawns the nord recruits for player red instead of yellow.

How can I do this? Thanks
