New 370Z owner in Denver!

Congrats on the purchase. Not many 370's around here. I'll try to answer your questions as best I can.

1) yes the Puralator filter is better. I use the Mobile 1 M1-108.
2) Mobile 1 has been great for me. Although I'm considering amsoil.
3) The K&N's are pretty well reviewed here. I went with the Injen long tube intake.
4) I believe you would need different rims to clear the sport brakes. Maybe spacers would do?. There are aftermarket options though.
5) The 370Z is not Direct injection.
6) I'm not very well versed in wheel / tire combos.
7) Most bolt ons don't give huge gains but Test pipes/ high flow cats and an aftermarket intake are a good start for 20+ HP. If you go K&N drop in filters you can get Post MAF tubes to increase the gain.
8) Just have fun with it.
