While most of this is already in that handbook, here's a bit for binders:

Take Improved Binding. Don't ask questions, just take it. See what it does. It adds two levels for the purpose of deciding what kind of vestige you can take. That means it allows you to take a second level vestige at level one. Since you are level one, this will be useful your entire campaign.

Also, for prestige classes, take Knight of the Sacred Seal. That is all.
