For normal/small pages it isn't necessary to use compressed and/or packed css/jscript-files (in my opinion).

If you still wan't to save some kb, try one of the minifying plugins for wordpress or try to use the compression possibilities of the webserver (i.e. mod_deflate for apache). Another way could be using the precompressed files that are delivered with floatbox (if you wan't to use them, you have to change source code of floatbox plus).
