Stick with the OEM NGK plugs, or some use RX-7 plugs which are cheaper but I believe you need extra washers to prevent damage. I'd rather pay a few extra bucks to avoid that issue and besides the RX-7 plugs will need more frequent replacement. You can find the OEM plugs for significantly less than what the dealership charges.
Change them when they need to be changed, or 35,000 miles whichever comes first. Depends on your car and how its driven. Some have gone past 40,000 miles on original plugs. Some change at 10-15,000. If engine is running fine leave them alone until the 35,000. If you have roughness or a recent flooding event a change may be warranted. If you want to keep tabs on how your engine is performing, learn to "read" the plugs and take them out for a visual inspection every so often (say 10,000 mile intervals or if there is a change in performance).

hey roachboy: The answer you seek is actually found in a few different places.
1) I highly recommend you read the owner's manual for our car. Trust me, most manuals are absolute JUNK, this one is the exception. Tons of useful info in there regarding this car.
IF you don't have a copy of the owner's manual, you can go to www.mazdausa.com and register under the owner's section. You'll need to enter your VIN and you can download a PDF version of the manual. (the site also alerts you of open recalls, lets you track maintenance records, etc)
Now, since I'm in a good mood I'll give you the answer.
Jack up the front left side of the car, remove tire, straight back are the spark plugs. There will be 2 per rotor.
If you have an extension for your ratchet and a swivel socket you can ge to them fairly easily.
Also, check the DIY subforum, there's a thread on changing out the plugs.

stock NGK's are typically the best solution for non-turbo RX-8's
