Your RPMs will go up but the gass consumption is minimal... I find I get about 10 MPG around town with my combo but I get about 20 on the hhighway... around town I tend to be pretty heavy when I find nice open roads...
as for power... gears wont change your power.. they just make it easier for your car to get moving.. it's like riding a bike, try pedaling your bike from a stop in a HIGH gear, you'd have to stand up and pedal really hard to get yourself moving... then try the same thing in the lowest gear... you'll pedal so easily, you'll start to move really easy...this is basiclay what you're doing with your rear end... make it easier to pedal.. for your engine... you'll lose top end speed.. but how often do you drive 140 anyway...
it's a good swap...
as for the seats the kits from 50 resto I believe come in both FULL leather or OEM style leather seating surface... I went with teh vinyl and I'm pleased with with... its alot cheaper and however you go the install is pretty easy... I did it myself you'll need some hog rings and hog ring pliers... it'll be worth it when it comes to setting those rings
