I happened to discover this cool Illustrator feature called "Make Pixel Perfect" which does fine grained alignment for you, which helped me after a manual shape resize.
I'm trying to improve my blog thumbnail photos and started with my default thumbnail, which is just my logo. I ran into an issue when I resized it - the shapes weren't perfectly aligned. Give Make Pixel Perfect a shot and see if that works for you.
