Door guards...shaved off?

I am not sure what they are called. Door gaurds...side moldings? Anyway, I am talking about the molding that runs on both sides of my car. I want to get that shaved down and then repaint. My question really is, roughly...how much do you think it will cost me? Also for the rear area on the trunk (the indent where my licence plate is at). Its a 96 Civic 4 dr. Thanks for any input.
