Hi Nick and welcome:)
For passing inspection:
- sway bars are fine
- chassis must be intact, so no severe rust damages, cracks or bends
Are the subframe connectors welded or bolted? (Welding on the subframe is only allowed by licensed chassis builders)
- The cam should be fine, so are the heads.
The inspection will do a emissions test by a external oxygen sensor from the tail pipe
- emissions diagnosis via OBD II is only on newer cars (must be +2008)
The emission test runs (engine warm) once for 30s at half of the rev. Limit, than another 15-30s at idle. The test contains the stoichiometric λ (1:14.7 = 1.000) as well as CO-Level (must be in the ppm range)
In my opinion the only problem could be the high flow cats, if they are not efficient enough (do you know the cpi-count?)
- Clutch, springs, lifters, and other internals are not "seen", because the inspection is not allowed to disassemble your car. Therefore they cant see them

- For lights, the camaro guys will eventually answer as well.
The first inspection will be a so called § 21 - your Maro will be fully inspected. This can be costly, but it's needed to get you a Fahrzeugbrief (pink slip) and a Fahrzeugschein. The Fahrzeugschein is like the ID of the car, the Brief is the actual title. Both of them will be handed to you after passed inspection and registration.
Wheels are important as well, which combination you've got?
And it would be great if you can share us some pics of your car
