Good question! Two sites that seem useful are http://positioniseverything.net/explorer... and http://css.nu/pointers/bugs-ie.html - they both seem to have good descriptions and workarounds.

I've been trying to find a few sites that have a comprehensive list of CSS box model hacks to make IE behave. I'm fairly new (6 months) to CSS and am noticing that IE treats things like padding fairly different than FF. I've also noticed that the indenting of unordered lists is wonky. Are there a set of hacks available that will bring this in check? It is very frustrating.
