To get the air box off is a 10mm and 5/16 hex socket or nut driver.
For the plugs, as has been stated you should do a few things, and I'll add another.
-> After the wires have been pulled from the plug, blow that area around the plug with an air nozzle to remove dirt and sand that can fall into the cylinder when the plug has been removed.
-> With a cold engine, spray a little Liquid Wrench down around each plug and allow to sit overnight before removing the plugs. My 6 year old 25K mile plugs almost fell out doing it that way.
-> Get a descent spark plug socket with the built in swivel.
The anti-seize subject is a wicked one. If you use any, make sure it is nickel or copper, and use VERY LITTLE. Adjust the torque down 25% too. I used no anti-seize, and full torque when I did mine. I will repeat the Liquid Wrench method next time I remove them.
On your new plug wires be sure to use dielectric grease on all of the boots. If your wires do not come with the grease, buy some at the auto parts store.
