Bosch plugs are generally coated with an anti-sieze coating. They are usually gapped correctly also but it's good to check to make sure.

Getting the pliers is a good idea but they are expensive. In any case, be careful removing the plug wire so that you will not damage them. I had all kinds of trouble until I started spraying the inside of the plug wire boot with HD silicon and now they come off with little effort.

I'd also recommend going to Sears and getting an inexpensive torque wrench (about $20). These cheap ones aren't as convenient as the better ones but they work fine for things like plugs.
