So yes, all of these are already active in MoI by default.

Sorry there isn't any way to set this part up for zoom, you will need to pick either left/right or up/down. In MoI v4 there is a setting in moi.ini for choosing which one though. To adjust it go to Options > General > "Edit .ini file" button and inside there look for:

[View]
<....>
MouseZoomLeftRight=n

If you switch that to =y then Alt+RMB will zoom with a left/right motion instead of up/down.
