I think it all depends on where you want to tailgate at.

You should decide if you want to be East or West of the Stadium. I can't tell you much about the West side, that is the new Title Town area. There are a couple of bars on that side of the stadium but that is the side that the Interstate runs by not too far away and the Packers have grabbed all the land there for the Title Town district.

The East side is where all the bars are. You have Stadium View, The Bar, Anduzzi's, Green Bay Distillery, Brett Favre Steak House. There is a great lot just behind the Green Bay Distillery, that charged $15 per game last year, that is 3 blocks from the stadium and just on the edge of all the bars on that side of Lambeau. They also have plenty of room if you have your own grill and want to cook out.

Definitely take the stadium tour, see the Hall of Fame and go to the Packers Locker Room "under/below" the stadium.
