The only other two peices of equiptment that will need to be attached to the attiny is a LED and a piezo buzzer. If it comes down to it i could just use 1 pin for both of them.
You're already out of pins...

@danieljay I am not sure if I read over everything correctly but in the end would this process allow me to only use 5 pins out of the 8 total? Leaving me the reset pin, and the two analog pins (physical pins 1,2,3) to use for outputs?
Two of the "8 pins" are Vcc and GND - can't be used for anything else.
If you reconfigure the RESET pin for input/output you won't be able to upload programs to the chip. You only get one upload (unless you buy a special programmer).
The only realistic way to do this is to add something like a 74HC595 to the system to gain 8 output lines then connect the Nrf24L01 control pins to that. The Nrf24L01 driver will need a lot of modification to get it working.
