How should I finish this dresser?

I am in the middle of converting a dresser into a TV stand. I plan to leave the top three drawers out so I have space to put my cable box and decorative items. To do this I have to add a shelf to hold them. So my thoughts initially were to cut out the back two supports that run vertically to add the shelf in one piece. Now I might add it in separate prices and not cut the supports out. Next delima I am having is to whether or not to add tile to the top. I have sanded it and added wood filler where needed but the top of the dresser got water damage from the previous owner. It kinda bubbles in a couple of spots. So what are your thoughts, opinions or what would you do?
