Planning to mod n/a, what and why?

Hey guys,
My wife and I are planning to mod her n/a 01 Rs.
Turbo swap will come in the future if she feels the need for it but I figured a little more throttle response and power would suffice for now.
Below you will find a list of what we will install and certain others items we might be looking into.

Certainly will install:
Cobb tuning intake
Borla headers
Borla catback exhaust

Items in consideration:
Lightweight crank pulley
Injectors (what brand, size, and where?)
Cams (brand, where?)
Chip/access port/tuning (not to sure where to find info on this.)

Any and all help would be appreciated!
