To replace the plugs, there is one bolt holding each coil pack on. Remove it and then you will have access to the plug. The rear ones are tough because of limited access, but take your time and you'll get them.
As far as a tune up, there really isn't that much to do. THere are no plug wires, distributor cap, rotor. I would recommend replacing the fuel filter and making sure the air filter was clean.
If you have other questions, let me know.
