I love the two-finger right click... When I use a different laptop it always confuses me at first when I can't two-finger click. The only downside is that you can't really then use the two-finger scroll in Safari with that option turned on; it always thinks you want the right-click menu. Small price to pay, I guess.
Another neat trick that has become second nature is hot corners. You can turn this feature on and customize its function under the "system preferences" expose panel. At first I thought this would be more of a hindrance, constantly accidentally hitting a hot corner. Now it's become essential; I rarely use alt+tab any more, and again its something I always miss when I hop on a different laptop.
I have it set where the bottom left corner shows the desktop, the top right shows all the open windows in an application and the bottom right shows all open windows. When you're ready give it a try and after a while, I guarantee it'll be second nature in no time and it really adds functionality IMO.
