8.51 % or 5.49 is not any high CTR. You got nothing to worry about. People even have CTR more than 25 % they are still part of AdSense.
hmm Nothing to worry about, so far, keep a close eye on your stats. There is nothing to worry now, as the day goes by different ppl visit your site some ppl might click and some might now.
Big G is always watching your stats and will tell you one way or another if they catch something fishy on your site you can still review your http logs and see how is the activity of the site
If you made changes to your template and your CTR increased that's a good thing, heh. As long as you didn't do something that would put you in violation of Google's ToS anyway.
