Getting Started in FPV: Questions About Gear and Setup

Hi guys, just decided to get into FPV after many years of dreaming.

I have a question, maybe it's really dumb but for me, this isn't obvious.

I have bought a master pocket radio(also bought a elrs-reciver at the same time) to train with liftoff before going trying the real deal.

So at the end of the month when I'm getting paid I will buy a set of walksnail goggles L, the walksnail nano/mini kit(which one?), a frame for a 5", motors, propellers, ESC and controller(speedybee combo?), batteries, battery-charger.

While it's fun to read about everything and watching videos to learn. I just must ask if it's something that I forgotten or completely misunderstood in what I need? I have many years in building projects with Arduinos so soldering equipment and stuff like that isn't a problem.

Thanks for the site and the possible help, and sorry for the long post.
