GPS device help.

Hi, I'm new here and just needed a few pointers. I want to make a gprs device and have picked some parts to put together, I just needed someone to tell me if I'm missing anything? I want to use a adafruit ultimate GPS breakout with a SIM800L GPRS GSM Module Micro SIM Card Board Quad-band Onboard TTL Port. Would this work and is there anything else I'd need? Thanks
