You do not want to do this, it would be bad.
The easiest way to move your stuff is to use the Migration Assistant. That application is located in the Utilities subfolder folder of your Applications folder. Follow the prompts once you open it. You'll need to connect your MacBook to your MacBook Pro via Firewire. If your MacBook does not have Firewire, another option is to just backup the documents, iPhoto library, iTunes folder, etc. to an external hard drive and move them over that way. If the MacBook has Leopard, and you use Time Machine, you can also restore from a Time Machine backup from a USB drive. In that case, you can just run a complete Time Machine backup on your MacBook and then hook it up to your new MacBook Pro and open the Migration Assistant.
Good luck!
P.S. Why do you want to move the actual drive from the MacBook to your new MacBook Pro?
