1. can you please tell me where to edit the verify password field so i can remove the title & add pre filled text
Edit your password field within CB > Field Management then set "Label for the verify password field:" to _UE_BLANK. You can add a pre-filled value using the "Pre-filled default value at registration only:" in the same location, but it's just going to be a bunch of stars as password fields hide values.
2. on all fields is there a way to make the pre filled text auto remove itself when a user begins typing instead of having to remove the text before they type in their input?
No, there's no parameter to add a Placeholder. Placeholder only recently became valid HTML with HTML5. In the past the only way to do this was with clunky Javascript. With CB 2.0 we'll probably have a placeholder parameter to easily have this.
