Selecting a pump and filter for an Intex 22' x 52" pool

I am looking into purchasing our first pool, an Intex 22x52 from Walmart. We want a pump/chlorination system that is the least maintence as possible, and are considering a combo sand filter pump/saltwater system. For a 22 inch pool, what size pump/saltwater system do we need? I don't want to purchase something too big, but also want to keep the maintence as low as possible (I know there will be some...). Also, from what I've researched, it seems like the saltwater system is preferable over the typical chlorine method. Thanks for your help!

A 22' Intex has about 10,800 gallons, filled.

Either the Hayward or the Intex combo below should be acceptable. The Intex has more features and capacity, but I'd guess the Hayward is more reliable.
