In addition to the Neue Pinakothek on Monday, you could also visit churches and examine non-museum art & architecture -- for example, the Asam Church (Asamkirche) in the Sendlinger Str. is quite something for high baroque.

And I'm with several the others on the Autobahn -- avoid it and just take the train to Salzburg (first choice) or Innsbruck.

Be sure not to miss the Lenbachhaus -- some cool art there & not as high profile as the Pinakotheken.

Have fun; that's a great area.
