Plugs are located under the long black plastic strips going down the center of each valve cover. You will need to remove about all of the black plastic covers on the front top on the engine as wires and dist caps are located under them. Pretty straightforward as you just look for the small bolts that retain them. Dist caps and rotors should be replaced at the same time. Not sure about plug wires as they are really very durable and reliable on this vehicle but it is your choice.

I have also read from others;

OEM wires are best (at least over Bosch) and to stick with them.

Irontoad.com

dont get those bosch things! they are bad! they brake when you pull them!!!

only OEM wires and denso IK20 spark plugs! nothing else!

also rotors and rotor caps should be denso too. they are OEM suppliers for toyota
