Chris,
In answer to your questions;
1. Will the adjustment of the gas block affect accuracy? Maybe. It won't affect precision but may affect accuracy with harsher recoil influencing flinching and jump.
2. How do you know if a gun is over gassed? You can use the ejection pattern as a guide. Look where the cases are ejecting relative to the muzzle which is 12 O'clock. Normal ejection is about 4 O'clock, but cases ejected further to the front of the rifle is a sign you are overgassed. Or, you can almost close the gas off and fire single rounds as you open the gas one click at a time, until it locks back on last round. Then go one more click for good measure and stop. Obviously some factory loads have more oomph than others so you can fine-tune the AGB for the ammo you are using.
3. If over gassed will it harm the rifle over time. Maybe - if it is good quality you can hammer it while overgassed and nothing will break, but it is unpleasant to shoot. Everything wears out eventually and you will never know if whatever needs replacing is a result of being overgassed, so best not to do this in the first place.
4. See attached picture of shell casing. What is causing the small indentation. That 45 degree little ding? Unsure. Is it on every spent case or just a few, or only one?
