Tif,
Regarding the firmware and the satellite list. I recommend that you use the file available here: FTAFirmware for Coolsat
You will need the CS5000 - 006 - 2009/12/23 file, the other one is for the 6000 model. If you upgrade the firmware with this file, it will have a satellite list included with some transponders, but no channels (you do have to scan for those).
The only other firmware that would be recommended would be the factory firmware from about 2005. If you bought it used, it may very well have a hackware version installed. I would install the firmware version that I mentioned to be sure, safe and legal. It also has a lot of nice perks to make setup and maintenance easier.
ADDED: Please read the guide here... http://www.satelliteguys.us/fta-mpeg2-faqs/190527-how-set-up-motorized-ku-band.html

Yep thats the firmware I have installed. So at least thats right.
