I changed my distributor cap,wires and rotor 3 weeks ago,but I did it on my '96 accord. I used a phillips screwdriver , a ratchet and asocket (i don' remember the size,but just try betweeen 6 or 8 mm)
Ok my Haynes manual said that you should disconnect the negative cable from the battery,but I didn't do it .
this was my procedure:
-unscrew the 3 retaining screws
-remember never to mix the wires from the old cap when attaching them to the new one!.You should remove each wire one at time and replace them in the new cap in the exact same location,otherwise you'll have a misfiring order .
-replace the old ruber gasket with the new one.
-and replace the new cap . that's it

you usually change also the ignition rotor when chaging the cap and wires,when you have already removed the cap check the rotor for any rust ,chips or anything that looks like corrosion or wear ,if it's ok go ahead,but if I were you I'd change cap,rotor and wires@ same time.

let us know if you're going to change the ignition rotor so we can let you know how to remove the rotor .

bye
