Menu Bar Lines and Menu Text Bold

Hello - promise I've looked through all the posts and haven't found answers yet. I just bought CatchBox pro and have 2 quick questions. My site is DecorDude.com 1. How do I make the menu bar options (Home Decor, DIY Projects, Gift Ideas) bold? 2. How do I get rid of the lines in between the different menu options? I want to try and make it one solid bar so it looks nicer. If I can't get rid of the lines in between menu options, maybe I can change them to the same color as the menu (#87240f)? Many Thanks! -Dave
