I can help with the second question,

Cree and Seoul both use the same diode but the Seoul is rated at 240 lumen at 1 Amp and the Cree is rated at 200 Lumen at 1 Amp. I heard Seoul states the maximum efficiency and Cree states the average. The Seoul has a positive die which might cause shorts and the Cree has the + and a - contract on the bottom of the die. Cree has a narrower beam then the Seoul and requires a deeper reflector to focus well while the Seoul only requires a small spacer to get the correct focusing height. The Seoul is almost a direct replacement for the Luxeon.

Sorry if that confused you, I can't explain things well.
