I haven't worked on one of those engines (I'm more of a Gen II wagon fan), but those problems could just be it's time for routine maintenance... Change your spark plugs, wires, cap, and rotor, check for vacuum leaks (vacuum hoses, brake booster, stuck evap, intake gaskets, etc), clean throttle body, clean MAF sensor, check temperature sensor, clean idle air control valve, adjust idle throttle stop, change fuel filters, check fuel pressure under full load, etc.
Some lifter tick is normal with that many miles - you can try various flushes and such, or just live with it.
It sounds like this car is new to you, so keep a close eye on the oil level until you know just how fast it uses it - running it with no oil will make that engine swap suddenly a high priority.
https://charm.li/ is good for quickly looking things up, https://project-car.net/technical-info/ has a pdf service manual, and you can google for other manuals... or ebay a full set. Will come in handy with the amount of work you plan on doing.
