Is m in E=mc^2 mass of matter and antimatter combined, or is it just one of them

-Thats right. Antimatter particles quantum values are opposite those of their normal matter counterparts -- intrinsic spin, electric charge, lepton number, etc. But their masses are exactly the same.......
Say, if I annihilated 1kg of matter with 1kg of antimatter, did I release 1 or 2kg worth of mass energy?

-
You would release 2kg worth of energy. The equation makes no assumption regarding the type of matter being converted. So for every particle of matter you need a particle of antimatter with the release of two times the mass on one particle in energy.

That's right. Antimatter particles' quantum values are opposite those of their 'normal' matter counterparts -- intrinsic spin, electric charge, lepton number, etc. But their masses are exactly the same.
