I'm like you. I'm never fully satisfied with the layout of my Apps. But for now, I am happy with how it's at the moment.
1. Main page. I leave the dock at the bottom how it was out of the box. I use my main page for the Apps I use the most in everyday life. The top half of the page is more, the social side of things. Messaging apps, social networking apps, etc. The bottom half is more, utilities.
2. Currently, the second page is used for whatever new Apps I download and are sorted into folders.
3. Third page is just the stock Apps that come on the iPhone out the box, but these are the ones I never use, hence, they're on the last page. This page is never visited.
