Set up breakdown

Howdy, I’m trying to get into air sim after years of air rb, and I’ve seen a lot of different posts in this sub about joysticks (seems like two, one for throttle, one for controls), pedals, and VR? But I’m not really a tech savvy guy and I have to admit I’m a little confused. Could someone break down what’s actually needed to start, and what’s it needed for?

Any gear recommendations or just plain tips would also be appreciated. Thank you for your help!
