I remember reading a topic once about how to remap the mouse buttons to work like they would under OSX, namely to do a right click when pressing option-click. After upgrading from 9 to 11, though, these settings were gone and I couldn't find this information again. Could anybody point me into the right direction? Which settings should I edit to customize right-click behaviour?

Not sure what settings allow right-clicking with the mouse itself, but at least in MintPPC 9 'F11' (I think, have to be double-check) acts like a right-click, much as control-click does in OS X when used with a one button mouse, except F11 is used by itself to simulate the right-click, without having to press anything on the mouse itself. As far as I know it has to do with remapping keymaps, but I'm not familiar with the process.

In /etc/default/mouseemu

#MID_CLICK="-middle 0 0" # disable
#MID_CLICK="-middle 125 272" # Left Apple Key (LEFTMETA) + click
#RIGHT_CLICK="-right 0 87" # F11 with no modifier
#RIGHT_CLICK="-right 29 272" # Left Ctrl + click
#SCROLL="-scroll 56" # Alt key
#TYPING_BLOCK="-typing-block 300" # block mouse for 300ms after a keypress

uncomment the line (and modify) which fits your needs.
I use
RIGHT_CLICK="-right 125 272" # Left Apple Key + click

This is an awesome explanation of how to set up right-click! Thanks for sharing the information.
