I bought a house with a pool and knew nothing before moving in. I skim it every couple days and check the chemicals once a week. Nothing to it.
I found this site to be very useful
Maintaining Your Pool | Pool For Thought
Chlorine tabs, some shock, backing soda, borax, test strips... just about all you need. Keep an eye on the filter pressure and back wash when required. Keep the water level up.
No experience with a salt pool.
