Every time you reach for your mouse, find a way to do it with the keyboard.
Use the command-T, command-shift-T, and command-control-T key combos. You can do almost anything with just those three.
Install "Edit in TextMate" in the TextMate bundle. Very handy!
Create snippets for each CRUD based controller action. It saves a lot of typing if you are doing REST.
Command-option-down arrow and command-shift-option-down arrow are a godsend when navigating a Rails project. If you try to go to a view which doesn't exist, it will allow you to create one.
Use command-tab to quickly switch between TextMate, Terminal and your web browser.
Hold down option key when moving the cursor left and right with the arrow keys to move one word at a time. This is extremely useful when trying to get somewhere within a line. It's much easier to hit the arrow 5 times instead of 20. You can do the same thing when making selections and deleting.
