The Advanced button takes up a lot of space and looks a little awkward. Also there are inconsistencies between expanded states. It'll be best to follow the structure of the orgsetup_roadmap.tmpl or orgsetup_expectations page - Roadmap has 4 columns, and setup page has 3. Basically one "table--cell breakalways" div and then all the column divs inside that where you can set the widths of those columns (10% for the button or something). So Let me know if you have trouble with this and I can help out.
