The easiest way to get rid of the map on the about us page is to just delete the map div on this page:
<div id="wagmp_map_1" style="width: 617px; height: 400px;">
For the categories being too long for the area I'm not sure exactly what you mean about this. A screen shot or a link would be best. You will probably just need to update the css for what you are seeing but I will need a reference for this to point you to the correct location to make this update.
As for the titles that are being cut off try escaping any quotes with a \ like this:
\" or \'
