Q:

How do I disable Safari-only mode?

I have no desire to enable Lion's Safari-only mode. I have disabled the guest account but still see the guest login item when I reboot my system.
Is there a setting somewhere I'm missing for disabling the Safari-only mode?

A:

You can disable the Guest account at startup in System Preferences -> Security & Privacy -> Advanced (the button at the bottom of the screen. The checkbox says "Disable restarting to Safari when screen is locked". I believe that it leaves the iCloud settings unchanged.

This works without changing iCloud.

A:

This guest account is tied in with iCloud's Find My Mac service in System Preferences. If you disable that service, the Safari-only mode (and the subsequent Guest account on the login screen) will also be disabled.
