Yeah, but if you turn syncing off, you don't get push messages, so no instant notifications if you get an e-mail or something (that's a no-go for me). As for the radio toggles, you're right. Now the radios are not 'powered' unless used by an app (but if active they do use a marginal amount of battery when in stand-by, though). BUT when juice is a matter of importance, whatever you can get is good, so turning these off is good practice.
