Remove dash, name that part & steering wheel.

First picture shows the chrome piece with the holes (and newly purchased rings) that receive the convertible top's lockdowns. What is this piece called? Since it is a single piece with no screws is it removed by simply prying up?
Second picture is inside the car looking at the top of the windshield. This piece splits at the rearview, each side has 1 screw holding the visor arm and 1 screw which I imagine is just to hold the entire piece on. Each side also has a light which you can't see because I removed them and taped the ends of the wiring because this is the piece that I am getting water out of. Then covered the holes with duct tape. I don't think I need to replace these pieces, but I do need to be able to take them off to see what kind of damage has happened from water getting in there (and possibly see WHERE the water is coming in) As stated earlier, I just purchased those rings you see in the holes for the roof and that may have been the issue all along. I purchased this vehicle about 6 months ago, unaware of the water issue, the rings were not there I just discovered them laboring through autoparts sites. It's a great car but I need to make sure I have these problems addressed before undertaking interior restoration.
