I drive my car 70 miles round trip with my 4.10's and haven't looked back since. If your looking for 12's don't even bother with 3.73's. Get an Offroad H and pullies that will give you a good 15-20 HP. I have a MAC but if you don't mind spending the extra $$ go with BBK. Both will fit but BBK fit and finish has a better quality. Not sure about the long tubes but something else you could consider is having your car dyno tuned. Mail order chips won't do much but a custom tune can add a good amount.
Throttle body and MAF will only give minimal gains on our 2v cars. Maybe 5HP total.
