To get started I'd just use software SPI so you can use whatever pins you want. Connect GND and VCC up to GND and 3.3v, then connect each pin to the easiest available IO pin.

Hi! I guess it's this one? https://uk.banggood.com/1_8-Inch-LCD-Screen-SPI-Serial-Port-Module-TFT-Color-Display-Touch-Screen-ST7735-p-1414465.html?cur_warehouse=CN

In terms of the software, probably start out with the ST7735 and copy the code from https://www.espruino.com/ST7735
It should be pretty straightforward to map the pins given the data above, but any questions just ask :)
