Does this battery fit all DeWalt 12V MAX tools?

Yes. It uses the DeWalt 12V MAX battery interface, so it fits the drills, drivers, saws and other 12V MAX tools and chargers.

How does it compare with the 2.0Ah pack?

It holds more than twice the charge, so it runs longer between swaps. It is also heavier and taller, which you feel in compact tools.

No. The pack is sold alone; you need a DeWalt 12V MAX charger, which you likely already have if you own the tools.

DeWalt lithium-ion packs are designed to be stored on the charger without harm, but for longest life store it cool and partly charged.

Lithium-ion packs lose capacity in cold, and DeWalt advises letting a cold pack warm to room temperature before charging.
