The tool you'll need to break it out is a rotary hammer. Get one with a 4in chisel, like this. Last time I rented one from Sunbelt it came to about $90/day with taxes, a chisel, ...

I didn't have all baseboards off so I had to stop and do that, and the pantry and laundry rooms weren't emptied.Removing the couple of tiles below the water softener was "fun." My advice for that is, shut the water off at the street, disconnect and move it, wreck the tile below it and then reconnect and turn the water back on. You will absolutely need safety glasses or goggles. Thinset will fly everywhere! The way I normally see tiles come up is that they'll pop off with however much thinset attached and then you'll have to go back and remove whatever remains on the concrete. With a great big hammer and all your prep work done ahead of time it's really not that bad.
