Welcome aboard N3. Are you from Chicago by any chance?
If you want to add lots of add ons then vag-com/VCDS will be needed.
There are loads of things you can add depending on your current spec. Read through the forum for a few hours and discover lots.
You won't be able to add a rear camera to your RCD 510 unless you have a specific unit for the camera. You'll be wanting an RNS 510 before long anyway so can just add a camera to that. It's one of the things I'm planning on getting round to doing one year.
