aSince you don't have the license to use your work EDA/CAD at home, yo might want to look at this GPL'ed integrated design tool for your nex project. It runs under W32/Linux/MAC and has autorouting, loads of symbol and footprints, and Gerberviewer built-in. It can even do a 3-D renderin of your finished board.
