I am trying to replace the alternator on 1998 Chevy Camaro 3.8L, but I am having trouble disconnecting the solenoid from the alternator. Can I simply pull it off, or is there some kind of latch that I need to release first?

On the 2010 Chevy Camaro V6, that vent solenoid is on top of the rear cross member. You might be able to squeeze a VERY small hand in there, but the regular service procedure is to drop the cross member down. Sucks, as I just had to replace the same valve.
There is no relay box in a 1985 Camaro. There is a circuit braker built into your headlight switch and a separate one in the fuse box for power accessories. There are fusible links in the engine compartment but none are related to headlights. There is one by the starter solenoid and three up by the junction block on the firewall. One is for the block itself and one for the alternator and oone for the ammeter.
I would try replacing the plug-ins for the headlights first. Those will go bad although you can usually wiggle them around and get the lights to at least flicker. If not them then the headlight switch itself is likely bad. Hope this helps.
There is a heavy red wire that connects to the only terminal on the back of the alternator. The starter should have a smaller purple wire connected to the starter solenoid. A red (positive) battery cable connects to the top terminal of the starter solenoid. There also may be smaller red wires connected to the solenoid at the same connection where the heavy red battery cable connects. Hope this helps
Stalling does not sound like an alternator problem. You have concentrated on ignition issues, have you looked at fuel related issues, including fuel filter and injectors? Much, much less likely, but air filter would also come to mind.
This worked with my truck, hopefully it will with the Camaro: Connect the battery cables, if you have a key fob for the alarm, press it to turn it off. Use the key to lock and unlock the door. My alarm isn't as new as yours, and was an aftermarket one, so it might not work, and you may have already tried this, but it's worth a shot if you didn't. Is it a factory installed system or aftermarket? Re-post the question if it doesn't work so someone else can help. Good luck.
If the starter/solenoid is new/replaced, most likely the cable from the battery to the solenoid needs replacing or the connection ends saned and cleaned for a good electrical contact, Also chek the gound wire connections (if any)
