There are lots of ways to extrude (or fake extruding) graphics in After Effects. Here’s a Community Help search that pulls up several.
New with After Effects CS5 is the inclusion of FreeForm. See this page for a summary of some resources about FreeForm.
You can also use Photoshop and bring extruded items into After Effects from there. See this page.
