Here's a tutorial by Chris Meyer of the ProVideo Coalition to walk you through the steps to use After Effects to create titles for Premiere Pro projects.
After Effects offers a number of text animation presets to offer looks that can't be created in Premiere Pro. And since the Premiere Pro project is dynamically linked to the After Effects composition, titles can be tweaked and edited after they're integrated into a Premiere Pro project.
The motion graphic design work of Chris and Trish Meyer has appeared on major TV networks and Hollywood films. They're also gifted teachers and the authors of a number of books on Adobe After Effects. Check out their Amazon.com page.
