ive only looked at your first page, but:
your logo and the images acting as title bars on those boxes have such low contrast they are hard to read
at first i thought the design was good, but when i saw it was actually not your design it completely put me off. try starting from scratch and coding a page - in the end you will know that it is your design not someone elses and you'll be alot more satisfied with it.
"user info" should go. i dont need to be told what browser and os im using... and anyone that did wouldnt know what they mean anyways.
its a great start
