Site Navigation Issues

Hello,

I'm running Wordpress 2.6.2, Gallery 2.2.4, and WPG2 3.0.7 and am having issues browsing through my site. My homepage (http://www.jeffandcrystal.com) comes up fine. Trying to access Previous Entries in my blog (http://www.jeffandcrystal.com/page/2) gives a 404 error within the Gallery frame. Trying to access an old story (ie., http://www.jeffandcrystal.com/20051029/moroccan-lamb-stew) also gives a 404 error within the Gallery frame. Trying to access the Gallery Site Admin gives a 404 error within the Gallery frame.

I'm trying to get Gallery/WPG2 setup so that all albums are referenced by their name in the URL (ie., http://www.jeffandcrystal.com/v/20080905_CorrineAndAlex) and get Wordpress setup so that all stories are referenced by their posting data and headline in the URL (ie., http://www.jeffandcrystal.com/20080729/la-close-on-social-assistance).

Can someone please help me diagnose what is wrong with the current setup and help me resolve the issue so that Wordpress/Gallery/WPG2 is functioning as desired?
