I wouldn't do too much to that boat except for basics. Seats, rod holders, and thin I/O carpet should be just fine, I would also suggest to just repaint the bottom with antiskid paint.
I'll agree that any boat can be a bass fishing boat, I wouldn't want too high a center of gravity though in any small boat.
Clamp on seat bases will work also, but if you use them MAKE SURE they are secured so they can't move.
I fished out of my 14' boat for years with secured clamp on bases, but went overboard into a river at night while fishing from a friends small boat which had a clamp on base that wasn't secured.
