Lol I just copied and pasted lax's reasons for the most part here, because I agreed and am lazy:
Hart Trophy: Eriksson: 3rd in league points while playing with a team of AHL'ers, led them to a surprisingly good start
Conn Smythe Trophy: Malkin, carried the team to a cup
Vezina Trophy: Fleury, seemed impossible to beat this year
Coach of the Year: Calgary's coach deserves this for sure.
GM of the year: Gmang81. I had a good season, but Gmen pretty much stripped Florida down to nothing and made them contenders in a single season. That's incredibly impressive.
