site in question: http://bit.ly/Lcspfp Some people have recently suggested my homepage is giving out to much PR. Do I need to no-follow the "about us", "Customer Service" and "contact us" pages?

I have a site that I'm trying to rank for the Keyword "Jigsaw Puzzles" I was originally ranked around #60 or something around there and then all of a sudden my site stopped ranking for that keyword. (My other keyword rankings stayed) Contacted Google via the site reconsideration and got the general response... So I went through and deleted as many links as I could find that I thought Google may not have liked... heck, I even removed links that I don't think I should have JUST so I could have this fixed. I responded with a list of all links I removed and also any links that I've tried to remove, but couldn't for whatever reasons. They are STILL saying my website is breaking the Google guidelines... mainly around links. Can anyone take a peek at my site and see if there's anything on the site that may be breaking the guidelines? (because I can't) Website in question: http://www.yourjigsawpuzzles.co.uk UPDATE: Just to let everyone know that after multiple reconsideration requests, this penalty has been removed. They stated it was a manual penalty. I tried removing numerous different types of links but they kept saying no, it's still breaking rules. It wasn't until I removed some website directory links that they removed this manual penalty. Thought it would be interesting for some of you guys.
