First, to load style sheets dynamically you need to compile them into separate .swf files. This can be done with mxmlc (or in Flex Builder by right-clicking on the css file and choosing "Compile CSS to SWF"). Then, to load the style-swf, you use the StyleManager

StyleManager.loadStyleDeclarations("blue.swf");

When you want to switch between styles, you'll also want to unload the previous style. So, assuming you put the name of css file in your combobox, in your css_changeHandler you'll do something like this:

StyleManager.unloadStyleDeclarations(styleid)
styleid = pickcssComboBox.selectedItem;
StyleManager.loadStyleDeclarations(styleid);

See Loading style sheets at run time for more details.
