5 Adjustments on Small 5-Page WordPress Site

Hello On this website [login to view URL] I need a few things: 1. Install this YouTube Playlist player [login to view URL] 2. Change URL format to [login to view URL] instead of [login to view URL] 3. As seen on this video [login to view URL] when you scroll on the homepage the menu & other content at the top disappears - homepage content doesn't need to scroll so remove this scrolling 4. On photos page [login to view URL] when you click on Photo Lihtbox pop up should appear - this was working before but is now broken 5. On Music Page [login to view URL] make the BUY buttons lead user directly to PayPal for purchase of CD Need a skilled WordPress person to do these things right away Don't bid if you don't have sufficient work history Thanks JL
