I believe we've found our answers right there lol. If your car is running lean, its dangerous to be even driving it, nevermind RACING it. I personally wouldnt risk that. Clogged cats will also decrease power obviously. Many people have had problems with the bosch platinums, so I would swap in a set of Autolite Double Platinums, same as OE. Ive been running them for a while with no problems. And yes, a tune-up will make a big difference.
Put it this way, last year my best runs were 16.4's. Besides performance mods like headers and a cold air extension, the only other things I did before this years runs were maintenance things(plugs, wires, coil pack, fuel filter, oil change and filter...). Now I dont think headers and cooler air would drop almost .6 seconds off of my E/T's, so the maintenance items had to come into play. Just something to think about.
