The Wheel scroll lines field changes how many lines of text you scroll when you use the scrollwheel. If you wish to only have to tap once to perform a left click check the Single click to activate items checkbox. If you wish to swap left and right buttons on your mouse check the Left handed checkbox. Note that this also swaps the button on a touchpad.

The Cursor tab on the left lets you change your cursor theme which is quite useful if you are say running virtual machines so the cursor does not look the same in the host and the guest. To change a theme scroll down to which theme you want under preview but you will have to logout and log back in again for this to fully take effect.
