welcome to RF. You read right about the plugs. the hemi's work best with the stock champion copper plugs.....works out good because that is the lest expensive too.

I have run the stock champions, NGK R Copper, Champion Single Platinum, and Champion Double platinum. By far the Champion Single platinum were the best.

If you have the extra cash I run the Diablo Trinity and it is great.

As mentioned the oem champions plugs will be just fine with your ride. NGK V Plugs (5306 or colder range 4306) are recommended when you start really piling on the performance mods.

I ran champions just fine with my cam only motor setup and then switched to NGK 4306 when i added BV heads and 6.1 top ends parts.

Ditto on using stock plugs.

For the Predator, if you can get 91 octane or higher fuel, I'd run the 91 tune. There won't be much else you need modify a tune for until you get an air/fuel ratio measurement (usually provided after a dyno session) and maybe the rev limiter and speed limiter.
