Std dev or Std Error?

When reporting means, is it better to report standard deviation or standard error of the means?

Also, if I divide a mean by a number (e.g. mean weekly income by divided by 7 to get mean daily income), is it valid to also divide the std dev or error by the same number?

If you're just reporting for the sake of showing variability, then use standard deviation - the std err of the mean is really only useful when you go to compute confidence intervals and doesn't hold meaning on its own.

Answer to 2nd question - no.
