Re: Just a few quick questions.
1. find ".left .title .prices " in blue.css, or whichever extra css file you're using... and adjust the "max-width". I think.
2. find ".topbar" in blue.css, ... and adjust the background... I think it's an image but you can just replace it with your color choice.
I use a firefox color-picker add-on called ColorZilla, which you can use to hover over any element on a page and view the associated css. Also the addon Firebug can be useful.
