He's right, you're not gonna notice anything from intake, maybe that noise, but trust me the longer you drive it the more you'll dislike that noise. Maybe not on days you're feeling good but it'll be annoying sometimes.
A great feeling shifter feels amazing immediately, and to a point where if you ever go back to stock you'll cringe.

Just don't hoon with the lower octane and it'll be fine. It was very common even before computer retunes for drag cars to run pump gas on the streets and then switch to 110 or whatever for the track back in the day. And they would hoon the street, difference was traction. Street tires on untreated Street didn't put car under much load, timing and all that wasn't a concern.

I assume you're talking about plastics. Most mods I've done interior would be like a metal bracket I fabbed to mount a tach, that would mount behind that stuff. However I'm a mechanic that works on modified cars often and I've never seen a quality interior modification. Like those a pillar things to mount extra gauges. Theyve always been junk.
