As with all things HVAC, it is highly recommended that you not do the work yourself and have a certified HVAC tech come and properly diagnose and fix a problem.
That said the following resources should be helpful. First this page has some good basics: http://www.ehow.com/how_5021806_troubleshoot-heat-pump-coils.html. This page is also helpful: http://ingramswaterandair.com/heat-pump/tips-to-troubleshoot-heat-pump-coils. These primarily address cleaning the coils and determining if the heating/cooling fan is operating properly.
This link talks about how to determine if ice on the coil is causing a problem and if the ice indicates a problem with the heat pump: http://zenhvac.com/its-technical/heating/154-heat-pump-defrost-refresher-coil-icing-.

To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present. To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl.
