IMHO you're confusing the theme.html file with what you have custom blocks for. The theme.html code is loaded with very page, and the variables you're trying to call are not, and are definately not personalised (how does theme.html know who you are?).
Check the FAQ for information on how you can add the PM information to your theme file, or to a custom block. That should give you some ideas on how to add module specific information from blocks to your theme file.
