Denso Iridium IK 20 spark plugs for 03 WRX Wagon?

I just picked up a set of these Denso Iridium IK 20 plugs. I recognize that I will have to gap them in order to use them. But should I be selling these plugs and going for something that is a step colder? If so, what plugs should I go for?

At the moment, my car is stock...however in the future I plan on replacing up/dp, and doing an ECUtek reflash.

Also, for gapping, should I just use needle nose pliers with rubber to prevent scratching? What do you guys recommend?

Thanks for the help,
Justin
