changing spark plugs

i've been told that i should use NGK BUR9EQ for trailing and BUR7EQ for leading, are these good?
i also want to do a compression test, are there any fuses i need to pull to do the test? Any advice would be much apreciated.

Yes, those plugs are what you're supposed to use. About 95% of owners use them.

When you do the compression test, pull the "EGI Comp" fuse. It is located in the fuse block that is under the hood, on the driver's side fenderwell. If I remember correctly, it is the fuse closest to the engine, and is 30A.

These are the compression test results

Front 105ish psi

Rear 107ish psi

Are these numbers good/bad, and what is the life of my engine like?

Wow, those are damn good numbers. Its got plenty of life left. Also, I would recommend the EQP (platinum) plugs. They are only a buck or two more and will last longer and generally work better.

BUR9EQP instead of BUR9EQ, and BUR7EQP instead of BUR7EQ. The P just means they are platinum plugs.
