Reading the OP, not too much can be added, he did his homework and answered his own questions pretty much. The 256 might be OK, but I have never been a muilti-process person (one breaks they all break).

I too would go with a 250EX/cooler and PP50 and later upgrade to the CK torch, unless there's no budget issues, then I would get them all at one.

You will be very happy with that package. Also, call in and get Oleg for the best deal. Mentioned you are on the forum too.
