Does two-finger tap still need configuring? I don't remember, most of these customisations seem to happen in a subconscious routine whenever I set up a new Mac
That said, you can always use control-click for right-button functions such as context menus. Better still, explore the wondrous world of drag'n'drop which on the Mac works in many situations and often in smart and surprising ways.
EDIT: Also, familiarise yourself with the numerous keyboard short-cuts. I reckon I haven't used the mouse for copy and paste in a long while. Many of the short-cuts used in Windows work if you substitute control with command.
