General IE-FF-CSS Questions

Ok I am frustrated.  I have this site tha renders fairly well in ff.  The only problems there are:
1) On the home page and the sign in page there is a white space between the two gray horizontal bars near the top.  I wish that were not there.

2) On the "About" page there is a mysterious extra padding at the top of the ad on the right side.

The real problem is the way it renders in ie.  I would really appreciate knowing what I am doing wrong and what I need to know to be able to understand why these things happen.  It would be awesome of someone could say, "You did this but you should have done this and here is why".

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I would be more than happy to give you some pointers, but where do I look?

Concerning 'mystery' white-space there can be several issues at hand.
- Most likely culprit is 'margin-collapse', where a child-element margin is 'collapsed' to the parent. Some obvious routes to resolve this are: Removing the margin from the child-element, adding a border to the parent, adding padding to the parent.
- White-space interpretation. When pushing an inline element into a block style rendering, browsers are unclear about the white-space characters (space, tab, carriage-return) that used to exist between the formerly inline elements. This is always tricky to resolve, but if you can get away with it, make sure there is no white-space...

- Mysterious extra padding requires a look with firebug or the likes, I know of no common causes so I cannot even begin to dream up a solution :)
