stolen macbook and ipad

If you didn't have Find My Mac enabled

1. Change your Apple ID password to prevent anyone from accessing your iCloud data or using other services (such as iMessage or iTunes) from your Mac.
2. Change your passwords for other accounts you use with your Mac, including email, banking, and social sites like Facebook or Twitter.
3. Report your lost or stolen Mac to local law enforcement. They might request the serial number of your computer. You can find this information on the original box or receipt you received when you purchased your Mac.
4. If you insured your devices against loss or theft, contact your insurance company and report the loss or theft of these devices.

If you didn't setup Find My Mac, then "No." Even with that, it only works if one of the devices is connected to the Internet. Even if you could locate it, it's not like you would be able to confront and arrest the thief.

No.
