Without being pushy, I would suggest you hold off on installing that alternator and invest in a decent charger. Installing the alternator is much more of a pain than charging the battery and I bet your battery just needs to be topped off. return the alternator and even if you have to pay shipping it will be a wash. As the many charger/tender/battery threads hear can attest, your money for a good charger will not be wasted.

Also, I suspect many of your initial problems were due to a crap battery. Bad cell, intermittently bad cell, etc. That's enough to mess with the Camaro's brain.
This is good advice. Hook up a battery tender to the new battery. (Actually, use the terminals under the hood for convenience.) The battery tender will tell you when the battery is fully charged. At that point, when you go for a drive, the charging voltage should drop to 12.5 volts within just a few miles.
