Another CS5 tutorial on presets by Chad Perkins (below) looks more at the Behaviors presets. Chris and Trish Meyer shared a PDF selection on animation presets (including behaviors and text presets) from their book Creating Motion Graphics with After Effects. See also John Dickinson's 2-part overview (1 + 2) of text animation presets on Motionworks.
For more tutorials and resources on presets (Adobe gallery), see AE presets & projects round-up, After Effects presets & templates burgeoning (on the new preset networks), AEP posts labelled presets or Animation Preset, and of course AE Help's page Animation presets overview and resources.
Note: Don't forget that presets, tutorials, and templates are just a starting point! See "Your weakness is your strength" for community discussion on this point.
