I would get rid of the 468x60 and the 300x250 if u want the maximum revenue. They look nice but don't make any money. Try replacing with a 336x280 under the title, single ad will do. Don't put too many ads in the beginning as you can flood your own ad CTR/CPCs. Also see the Adsense heatmap in my signature for reference.
Yes, that's the best ad size and placement Only 1 adsense block per page also, for maximum adsense revenue Also make sure the ad block is text only and NOT text/image
I suggest not to use the link unit ad on the top to move just below the menu. Try placing the 468x60 AD below the content and replace the image with the 300x250 AD.
