You'll get a resounding "stick with the Toyota OEM" from here. I have no experience with the wires/coil packs, but the plugs you get from your Toyota dealer (NGK or Denso) are far superior to the crappy Bosch plugs that I had in there briefly.
With very few exceptions, when you're replacing parts or doing a tune-up Toyota parts are the only way to go.

Oh yeah, welcome! You'll find that it's a friendly and helpful bench around here.
