Rusted-On Rotor and Caliper, need help!

[nastynas]

I just started replacing all 4 brake rotors on my Talon. The front rotors and calipers came off without much trouble, but the back ones are being a real bi***. On one side, I can't get either of the two bolts off which hold the rotor on, because of the rust. On the other side, I managed to get one of the bolts off. I tried soaking it in penetrating oil, but it didn't seem to help. Does anyone have any ideas on how to remove these???

A socket and a long breaker bar

And then a torch (mapp/oxygen kit from Sears works ok).
