I vaguely recall seeing some ways to achieve at least some of this - either in the knowledgebase or a forum thread. Try searching on words like conditional, formatting, colo(u)r, etc.
Conditional Formatting of Text and Backgrounds
It appears that others are having the same diffculty as I am when multiple measures are displayed in a cross-tab as noted in these threads. These posts were made before the release of version 6, but I haven't found any information indicating that formatting options have changed in the latest release.
Addition of Marks
This thread deals with the addition of marks and text in columns of a cross-tab. I'll only want to draw attention to areas that require attention; in all other case I wouldn't want an arrow or other mark. For that I'd import a blank image for display.
This is one of those things that is not easy to do in Tableau. In order to get what you are looking for you would need to reshape your data so each of the fields you have on the Measure Values shelf are on a different row in the data Tableau is connect to.
