While I can't say for sure how much having every page linked to every other page will affect your ranking, Google has said in the past that it's probably better to have fewer than 100 links per page.
Google also suggests doing things that benefit your users. I'm not sure how useful having all those links on every page benefits the users because with so many choices, people start acting like deer in the headlights, and don't make a choice.
You might want to read this thread [webmasterworld.com] and then this one [webmasterworld.com] which describe Information Architecture, and how to use it properly to guide users around your site.
