What are some non- obvious things to back-up if I'm doing a clean install of Lion?

[ToddJ]

I am about to do a clean install of Lion and I just wanted to make sure of all the things I need to backup. Obviously photos, music and videos I will back up. I need to back up Mail's smartfolders, Rules, flags,etc. *Are there any other obvious things I need to back up that I'm forgetting.*

----------

Does anyone know how to back-up email so it keeps all the different color flags

Internet Browser bookmarks, Program preferences, the list is endless,

why not migrate from time machine?

because i was having a problem with iPhoto that couldn't be solved and might have corrupted something with my graphics card

~/Library

It's hidden but contains some important things.

Don't you have a time machine backup? That should just about cover everything, literately.
