While it is good to have as much MF as possible, is there a magical value where it is most effective, keeping in mind diminishing returns (If any?)

Uninstalling applications in Mac OS X is very different than uninstalling in a Microsoft 1Windows environment because Mac OS X has nothing like the Windows Registry.
Most Mac OS X applications (anything that ends in .app), like Safari and iTunes, are bundles. The application icon you see in Finder (typically the Applications Folder) is usually a special folder itself, made to appear as a single double-clickable file. These "folders" contain all, or at least most, of the files needed to run the application, ie they are self-contained. This means that to uninstall these applications, you only have to drag them to the Trash. If you control-click (or right-click) on an Application icon, and you see "Show Package Contents", then it is a bundle.
For Diablo III Beta, you just delete the folder, because it does not create Package Content for you to delete.
But it does create fill .txt files that are not part of the installation. Here is a screenshot of my Mac with all files with "Diablo" in their name.
And here's the screenshot with the "Beta" name search:
Aside from the Diablo III "Beta Setup" that is in my Download folder, there is "diablo3_beta_enus-driverinfo.txt" that is in /Users/Shared/Battle.Net/Client/Blizzard Launcher.1454/Support
The others files are inside the folder in the applications (or in the location you selected).
Also inside /Users/Shared, there are 2 folders called: Battle.net and Blizzard. They are created after you install any Blizzard Game like WoW or SC or Diablo. I don't recommend to your remove those folders, unless you are going to stop playing Blizzard games.
Almost forgot:
There is a file that saves your preferences called D3Prefs.txt the location is: /Application Support/Blizzard/Diablo III
Watch the auction house.
Right now, crafting materials are selling for substantially less gold than all but the worst low level blue items. You'll get far better results selling your blue items and buying Essences from the AH.
For example, current market value for normal mode mats is 20g for Subtle Essence and 45g for Fallen Teeth. So any item worth more than 25g, I sell. If its worth less than 25, I gamble for a shot at a tooth.

As you already mentioned "The more the merrier". But keep in mind that you should still be able to kill monsters. So if you go all-in to MF (almost) any enemy would probably be able to 1 shot you.
Concerning the diminishing return: yes, it exists but I don't know the exact formula to calculate it. Also, do not forget the Nephaelim Valor which you want to stack to level 5 which will give you additional 75% MF and 75% GF and bosses will drop at least 2 rares(1 rare in patch 1.03, but elite packs will also drop at least 1 rare in patch 1.03).
