Hey, cool about the new MBP. Some quick notes that may make your life easier:
There's a "ignore accidental trackpad input" option in Trackpad under System Preferences, which should cut down on finding your cursor wandering around your textarea or word processing document. The second, which I love, is under the Keyboard Shortcuts tab of the Keyboard & Mouse preference pane. The setting is "All Controls" under Full Keyboard Access. This lets you tab through buttons on dialog boxes or links in web pages, and more. Very nice.
