There are a couple of free multiple desktop additions to OS X for example DesktopManager http://wsmanager.sourceforge.net/
You can also place the Dock an the right or left side of the screen. You don't loose that much screen real estate that way.
As a Newsreader I use the free Halime.
To find OS X apps I always make a first search at sourceforge and then at versiontracker.com or http://osx.hyperjeff.net/Apps/ .
