Since the beginning of the month of August, my CTR is very low. I have recently decided to change all my ad placements to increase the visibility of the ads and my CTR of course. Okay here how I put them.. Single Post: 2 X 468 x 60, One at the top and one at the bottom of each post. 1 x 300 x 250, at the sidebar on the post page. Homepage/Page: 3 x 300 x 250, all of them at the sidebar on the homepage/page. Note: All the 300 x 250 are showing image ads only and the 468 x 60 only text ads. What do you think? Good ad placement or too annoying?

I think they are fine. In fact when I visited your home page in your blog the 300 x 250 are showing text ads and not image ads as what you've said. Just monitor the CTR a little while before coming to another conclusion.
from many experiment 250x250 works the best. at the middle of the page at side bar can be anysize that fit the size. at the bottom can be some skyscraper size.
There is so much text on your page, Google must have difficulty targeting ads. I was just blinded by all the text.
