For Blender I use these links
http://www.blender.org/ for the software and support
Blender is the free open source 3D content creation suite, available under the GNU General Public License, it works most operating systems.
I have used 2.54 before.
a cursor FX idea I had a while back using Blender, Keyshot and PS for post work.
http://blenderartists.org/ is the Blender community site....mine are simple renders
The renders on blenderartist, by others will blow your mind.
btw 2.54 is a beta, you can get 2.49 the latest
