You're going to get different opinions on anti seize on spark plug threads. I never put any on; the NGK plugs I've used specified that they're supposed to go in dry, since they already have an anti-corrosion plating on them. I've installed 24 spark plugs in the S10 since I've owned it, and never had one that got stuck. I've never used any on any of the plugs I've installed in cars, either.
If you decide you do want to put anti seize on the plugs, don't go by the recommended torque setting for the plug (if there are any). If you lubricate the threads, you have to reduce torque by anywhere from (I think) 20% to 50%, depending on what lubricant is used. You do have to be careful when screwing a steel plug into an aluminum head, especially in fine threads; too much torque can cause the threads in the aluminum head to strip.
