Hi,
Dashboard cracks are common on these older Cadillacs, there really isn't anything you can do other than replace the dash pad. You can find new dash pads on Ebay.com amongst other places. Usually they come in black or white then you dye them to match your interior.
Here's a good link about caring for your vinyl top. It also covers cloth roofs, but we know you have vinyl.

There's several products out there for dressing the vinyl, I like to use "Natural shine" by Meguiars. It comes in a clear red bottle and leaves a nice, low gloss, protective shine.
