I recently placed ads in a few different areas and since then my CTR has been all over the place, how long does it usually take to get an idea of if the new placement is good or not and for it to stabilize earnings?

It depends on how many impressions they get and how different the performance in placements are. Subtle changes in performance require more data to measure with confidence. You could use a statistical significance calculator like this one : [vwo.com...] (for "conversion" read "click").
