To remove spark plugs:
Step 1 remove engine:p
seriously,
1. remove inlet pipe from throttle body
2a. remove PCV hose between rockers.
2. remove cover plate (between rocker covers)
3. Unplug coil packs
4. Remove bolts holding coilpack frames in position.
5. Lift coilpacks up off sparkplugs.
6. Find you have the wrong spark plug socket, put it all back together, go get the right socket (smallish one), come home, pull it all apart again.
7. remove sparkplugs
I would start with (NGK) heat range 6, gapped down to 0.9mm. Since you're using coppers - dirt cheap - you can afford to have a couple of sets, so you could try a set of 7s later.
Not sure of the (NGK) part number, but its been mentioned numerous times in various posts - have a search.
