Default How cool should I go??

Gunna run a 3.4 MPS and wanna go cooler with the plugs and stat. Should I go with one or two heat ranges cooler for plugs? 180 or 160 stat? Whats the plus'* of each?

I would say a 180 t-stat, along with adjusted fan settings for the 180

180* is just fine, and even with that your going to need a PCM tune to turn on the fans. Being a 2000+ installing a 160* is going to trip SES lights

180 is good for the summer but if you drive the car in the winter you will probably switch back to a 195 for the winter.
