Stuck with a disappearing wp admin bar

I’m working on combining the functionality of two themes for a small project I’m running.

The homepage attempts to combine the functionality of two themes: Inspire, from Woothemes; and Network from WPMU Premium.

Unfortunately, somewhere in the middle, I’ve lost:

a) the WP admin bar — still available in /wp-admin, but disappeared from the homepage. (yes, wp_footer still exists).

b) I would imagine the network images should be clickable…and they’re not. They link to #.

Any help to debug this would be greatly appreciated.
