1. Is there a slice of PHP/code that I can look for in any plugin that would help me identify what fields the plugin is inserting or has inserted?

You can look for "update_option" and "add_option" in the plugin code. Those are the standard ways for WP plugins to insert values into the options table. Hopefully no plugins are doing direct inserts.
