What are the exact differences between the Golite Paradigm and the Golite Gamut? I know the Paradigm features pit zips and an mp3-player pocket but are there any other differences?

Secondly, I am considering buying this jacket (or the Paradigm) for a 3 week hike through Norway. The question is: will this jacket offer enough waterproofness to get through the entire holiday decently? I don't mind if a tiny bit of water gets through but I want to stay nearly dry. Will this jacket provide enough waterproofness for that or will it soak through early?
