Definitely get a copy of Win96 software by Don Starr. Get the computer hook up cable. Subscribe to this website so Win96 will program your scanner for you.
If you like to listen to 800mhz, get one of the antennas that's tuned for it. For in-car use, get an outside antenna (BIG improvement). I use the Radio Shack glass-mount mobile antenna.
Some place online sells leather cases. Sorry, don't remember who.
Have fun!
