Spark plug change?

Just bought a 2002 ES 3.0L w/62K miles. I had the timing belt changed and waterpump for good measure (I coulda done it but after seeing all of the stuff that needs to be removed was too lazy). I now want to change the spark plugs, wires, rotor and cap. I see that the intake manifold needs to be removed to get at the plugs. Looks sorta easy. Any advice?

Get a Haynes manual or repair manual and make sure you bag and tag everything you remove or unplug.
