Hope you're still reading - I highly recommend one of the third party mouse managers like SteerMouse or USB Overdrive or ControllerMate.
I found the arch of the Magic Mouse just too low and went back to the old reliable Logitech MX Revolution, but I will never install Logitech software again without an excellent reason. These packages will let you configure all of the buttons and SteerMouse (haven't verified for the other two) will definitely let you specify linear or accelerated wheel scrolling with variable degree of acceleration.
You can pinch to zoom, which will simulate Command ⌘+ and Command ⌘-
You can also try the extension, which was mentioned by in Danijel's answer.
Otherwise, you can hold down Control ^ and the screen will zoom in and out. It ends up looking like this though (which I don't think you want):

There's an extension called AutoScroll that enables scrolling while pressing a middle button.
You can also enable it everywhere in OS X with Smart Scroll. See this question.
To make middle clicking work with a Magic Mouse, you'd also need to install an application like BetterTouchTool or MagicPrefs.
