Use the related Threats and Countermeasures Guide in the Windows XP Security Guide to evaluate any threats to security, and use the Security Guide to learn about the tools and mechanisms for implementing the protection mechanisms. The irony is that people tend to turn EFS on for files they care the most about, and then lose them.
In that case their files become completely inaccessible. Occasionally someone will turn EFS on without backing up and then they find they need to reinstall the OS. EFS or other similar technologies are designed to thwart the data thief when the disk is in hand, but make sure to understand all the implications of EFS. NTFS security was designed to protect files from within the OS and via the network, not to protect files when someone has the hard drive and is intent on retrieving the data. It takes all of a minute or so to gain access to NTFS files if the actual drive or laptop has been stolen.

The BIOS password can, however, buy you time to change passwords, cancel credit cards, disable accounts, assess damage, and so forth, and might prevent a hacker from gaining access to personal information. You should definitely weigh the pros and cons of using these passwords. Lists of these passwords are in wide circulation and are easy to bypass by documented procedures (remove the battery and short the contacts, and so on).
