You'll probably want to go with a MOMO wheel, or something equivalent (almost ANYTHING is a vast improvement over the puny old NA wheel). I don't know what year your car is, but I used the Daikei Boss adapter hub to install a MOMO wheel in my '94 - it makes installation about a 30 minute proposition, with zero wiring hassle and no airbag light problems.
As for seats, I'm sure you'll get plenty of advice...
Good luck!
