I wouldn't paint it. But that's me. The material shouldn't be that expensive. Just more of a PITA to replace if it's still new though. If you do want to paint it, get some good fabric paint and fog it on there to get it to the darkness you want. Maybe try that first and if it doesn't get you where you want to be, then replace it with the right stuff.
If it's a full hard top, with the back window out, you should be able to drop it, tilt it a bit, and slide it right out the back. I've never done it that way, but can't see why it wouldn't work. You may have to bow it a tad to clear but it should come out. You could also get it out the passenger side by laying down the passenger side seat and working it out carefully but it's a huge PITA. But can be done. Easiest way is remove/install it with the windshield out.
Remove any dome lights, sun visors, coat hooks, upper and side trim, along with their clips. I know they make repro clips for the sides now, but you can re-use your old ones if you're careful. The front and back garnish molding clips along the top usually get broken removing the garnish molding, so you may need to get new ones.
If it's original, it'll be a pressed foam-board backing. It'll be old, so it'll probably be brittle too, so be careful of that. If it cracks, you can usually get by with some duct tape on the top side of it to repair cracks.
As for removing the material, I've only done it on crusty ones where the fabric just tore off and the fabric foam backing crumbled. Then I used a stiff plastic brush like one for scrubbing tire sidewalls to scrub away the fabric foam bits. Obviously using it dry. Not sure about removing the new stuff that hasn't decayed.
