Opinion on what? Is this an engine alone? If so, LS2 or LS3; what year; or an engine in car? Again, what year/style?
Provide more into when you post an open ended question like this.

If your existing plugs are good, its not going to add anything.
The thermostat is to allow the tuner to reduce the engine temps and turn the fans on earlier with the idea of cooling the intake temps down.
But you kind of want a hot engine and cold intake air..

The exhaust and CAI are the main things that will raise output. The rest really rounding errors.

Like you say, just fit whatever yourself and go and get it tuned if you like. A tune is probably useful as the airflow through the engine will have changed and therefore the base volumetric efficiency map should be updated.. It affects spark timing and fueling etc. Maf table will need recalibrating for new CAI etc, etc.

NGK plugs are crap and can mess with your electrical system in addition to (and I absolutely swear this is true) causing detonation at idle.

For reference A&A supercharger kits come with NKG plugs and they've shipped thousands of these kits that work well. I have NGK TR6 plugs that work great with my A&A kit.

Never heard this before either, my Corvette mechanic has done 1000s of builds using NGK TRK plugs with no issues. I have NGK TR6 in my cammed LS3 and it screams from idle to redline
