There's a branch that has support for such things: http://docs.codehaus.org/display/GEOSDEV/WCS+Branch But it hasn't had a release in awhile, and thus would be tough for a newbie to get up and running.
I do have some experience with programming Java so if the WCS+Branch is functional and allows tiling I would try that first. I would prefer a Java solution because I wish to experiment with some on-the-fly manipulation of source data and Java gives me the best possibility for this. I had tried sometime ago to get the WCS code to work but I was having erros associated with the HSQLDB database. Can you point me to somewhere where I can get info on getting the WCS-Branch to work.

Sure. You'll have to check it out from SVN and build it, as our WCS branch guys are over-worked merging to trunk on geotools. See: http://docs.codehaus.org/display/GEOSDEV/WCS+Branch
The svn command to do is 'svn co svn://svn.codehaus.org/geoserver/branches/wcs-branch/trunk/geoserver'
Then you'll have to build it, and you should be able to select your files from the web admin tool. I think 'WorldImage' is the right one. For better performance there's also an experimental imagemosaic datastore, but Alessio or Simone would have to tell you moreR
