put saved metabox values back into fields and then display on the front end

You want to get the data out of the custom post type, assign it to a variable, then echo that value into the field when the page loads. If nothing else, that will make your code a lot more readable (and easier to troubleshoot) While it’s not explicitly about what you are doing, you an see the exact method at work here (WP Stackexchange Post).

You may also find Justin Tadlock’s review of meta boxes at Smashing Magazine to be an enlightening read.

Finally, if you want shortcuts, a system like WordPress Alchemy provides a good code library for rapid prototyping and execution, whereas something like Advanced Custom Fields takes a more GUI approach.
