3a. Upgrade rare item (mostly for weapons, because they're expensive at Kadala)
3b. Convert set item (if you get multiple same set items)
4. Join open public games, and leech for gear (and experience)
Those are pretty much main methods of farming gear, at least basic ones. After that you should be able to do higher torments and higher greater rifts, and then start chasing ancient gear and get into fine tuning of gear (primary/secondary rolls, augments, etc)
Getting gear in D3 nowadays is pretty easy. There are several ways to do it:
1. Farm any Torment difficulty you can play with relative ease, rifts drop items decently, even in lower torments.
2. Gamble with bloodshards at Kadala
3. Use Kanai's cube recipes
