Here are my personal opinions..I am sure you will get a few different opinions from people on here.
I would definatly go with long tube..I bought shortys, they work well but I wish I had spent a few extra bucks and bought long tubes.
Not for sure which pipe to buy but I love my BBK off-road going through my flowmaster 40 series.
With a auto I would definitly go with 3.73
70MM throttle body I dont think will help you with this limited number of mods but it certainly wont hurt you at all..So I would go for it.
I would just stick with a fenderwell cold air mount with k&N filter..i think when u buy one it comes with the filter...
Leave the thermo alone unless you have heating probs, then switch to 160 degree
If you are all done with the mods on your car go have a chip burnt for your setup.
I would just buy a set of underdrive pulleys; waterpump, alt and crank for like 85 bucks..
I think another good investment would be a mass air meter. I know summit had vortechs for a nice price $125..If you can go without this car for awhile such as a few days, I would port and polish the intakes as well as the heads..A electric fan would also be another thing to do..Make sure your will be able to get traction!!!
Good Luck
