Great seats, just stick with the lower rows (rows 1-4) that way you can see everything and won't have a bunch of fans coming in and out of the rows in front of you. I've sat in the upper level for most of the Wild games I've been to. Looks directly at the net although sometimes you have to go by the crowd's reaction to know whether the team has scored or not.
The arena isn't at much different than the other NHL arenas I've experienced. It still has that new and shiny feel to it and there are plenty of hotels withing walking distance of the venue so you won't have to worry about parking.

There is $6 parking in the Children's Museum garage, you can also ride the 54 bus from Mall of America for rather cheaply too.
