What do I need to adapt my Canon PowerShoot A70 digital camera
to my telescope?

You need an adapter designed for afocal coupling (camera lens to eyepiece) such
as the Scopetronix Digi-T.

Are there any good web sites to help educate me on all of this?

The Yahoo digital astro group is a good place to start.
