It sounds like you're using tap-to-click. If you don't want to get used to the trackpoint you could disable that and actually depress the touchpad when you want to click. Setting the synaptics parameter "ClickPad=0" makes that touchpad work a lot like the Apple defaults. I've been using this configuration for 3 years and I never have the cursor jump around or misbehave at all.
