Programmer, What settings to use

I have a '00 3.8 Firebird (Daily Driver) and am looking for some advise on things i should change.
I have a Max Energy Programmer.
What should I set the Shift firmness to?(25,50,75,100%)
Should I change shift points?
I'm about to install a 160* thermostat so I'll set the fans at 160 correct?(after install)
I'm looking to get intake and exhaust down the road.
Any suggestions, input, advice, comments, or insults would be great!
