Is Autobleem the "go-to" emulator for a PS Classic? I managed to get one for ten bucks last year and have yet to mess with it
Autobleem isn't an "emulator" it's just an easy to use hack. You'll be using either Retroarch's emulator core or the "built-in" emulator from Autobleem/Sony.
IMO Autobleem is the easiest plug and play hack to setup, but you can go other routes like Project Eris and such.
Autobleem runs off your memory stick -> if you unplug the stick, it will go back to the stock setup.
