Dave's right on the PVA, it should just peal away, you might even be able to pull it away with your thumb nail.
As for the paint job, first things first, get down to your local art shop/stationers/hardware store and buy the cheapest acrylic paints you can lay your hands on and a cheap decorators paint brush. Make sure you at least pick up some black and white and either some browns or the primary colours and mix your own.
Prime the board black (use GW primer if you've already got some or buy a cheaper can at the local auto store) then mix up some grey paint using your cheap acrylics and drybrush the board, focusing on the raised area and cliff faces. Continue to drybrush on your greys, adding slightly more white each time and covering a smaller area each time. When you're happy with that, mix up some brown to a shade you like and stipple it onto the board in the areas you want to look brown. Like the drybrushing, stipple a little at a time and build it up with varying shades of brown.
Job done, enjoy your gaming board!
