Dave,
You should still be able to flip through your open windows with CMD-TAB. Once you're in a tabbed application like Chrome you can then CTRL-TAB through the open tabs within the app.
One thing I like to do is click the green dot in the upper left corner to make Outlook full screen. Now use THREE fingers on your trackpad or magic mouse to swipe left and right. You'll bring in Outlook or swipe it out and back to your other apps, no more looking for it or doing CMD-TAB to find it. You'll even find that you can swipe to a clean new desktop and start using some other apps there. Swipe back to your other desktop or Outlook easily the same way.
Other fun mac tricks: Swipe three fingers straight up on your trackpad and see all your open windows at once! That's called Mission Control. Hover over each small window and Mac will tell you the name of the document, XL, PPT etc. Go to Apple Icon / System Settings / Trackpad / More Gestures to see a bunch of other things you can do. My favorite is CMD-spacebar which opens Spotlight Search. Start typing the name of a document etc. and Mac will try to find it on your machine or give you other searching options.
Enjoy.
