This page contains some information about the Adafruit 320x240 2.8" TFT Display + Resistive Touchscreen.

This has all 40 pins GPIO pins brought out so you can connect a 40-pin GPIO cable underneath.

It uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25 and #24. All other GPIO are unused.

Since we had a tiny bit of space, there's 4 slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button.
