My experience with PLUG chaning is it is much easier to do with with HEADERS on, because the tubing frees up a lot more space to obtain the plugs. I have DYNATECH, which have similiar tube design at the top near the heads and it is VERY easy to change the plugs.

Honestly, I went with ACDELCO Iridiums, a bit pricey, but I get a nice discount at the dealership, so I don't pay that much. NGK has an Iridium plug too, but honestly the price insn't that big of a difference compared to the GM set.
NGK TR55s are a nice little plug and since NGK finally fixed their tips (used to be screw on tips and they always seemed to back out on my application). The 55s are cheap too.
How many miles is on your car now? The stock plugs are rated for 100K miles. You may just want to remove one or two and take a look at them and see what they look like, they maybe fine.
Perfect time to replace wires too. MSD are a popluar choice, I went with GRANATELLI, I like the TAYLOR wires too.
Pulled mine at 48k No wear what-so ever .. Clean... Purrs like a kitten.. Roars like a Lion... No need to change.. Plugs are good for 100k.. Some folks will argue that leaving the plugs in for that long makes it extremley hard to replace or take them out.. Which is a valid point for changing them out early. I guess the plugs kind of weld themselves into place after so many years/miles... We would'nt want to strip the threads... Make sure to use anti-sieze when replacing the plugs.

I was considering changing mine, due to the little unsteady idle I experience time to time. Am I looking at plugs or injector cleaner? I've got 35K miles on the clock as well.

Next time you fill up put a can of SEA FOAM in the tank and fill it up, this stuff really does wonders on the fueling system. If you are running a stock air intake setup, check the filter, maybe dirty. You could pull a couple of plugs and check them and take a good look at the wires. The intergrity of the wires can be impacted by heat over the years, cycling them. They can get old, just like tires regardless of how often or how many miles you have on them. My buddy did a wire swap on his '98 and it did a great deal of wonders on his car's idle.
