How does the Cosmic Microwave Background radiation temperature variation change over various time scales?

Is the CMB only red shifting in frequency or is there more to it, and over what time scales and distances would one notice a significant difference?

It only gets colder over time because of loss of energy due to the redshift you referred to; or at least we’ve seen no reason to believe it gets any warmer. The angular distance at which cmb fluctuations can be observed is approximately one degree.
