The text animation looks like a combination of layers with different transfer modes, and some random-looking motion applied with keyframes. Similar can be achieved with Andrew Kramer's "Twitch" plugin, if money is no object.
The glowing stars/spheres in the opening ID look like they were created in Trapcode Particular, but you could produce a similar result manually if you have the patience to create each particle (or group) as individual layers.
All of what Andrew said. You can find tutorials pretty much for each of the separate effects on Videocopilot.net.
