Is there a TTS app that will read me my email or a webpage? All I can seem to find is apps that read SMS and manually entered text.
For Email there is the DriveSafe.ly® Free SMS Reader available from Google Play Store.

It can read emails, but has mixed reviews. I have never tried it so can't recommend it one way or the other.
