FIELDSET/TABLE Padding

Another headache about FIELDSET. I have two FIELDSETs side by side ( left and right).
The left side is for Work Address and right side is for Home Address. They are almost same except Organization and Position in Work Address.

I try to make there two FIELDSETs in the same height with style sheet height:30em, but Firefox gets more space in the bottom.

Finally, I find that IE will have margin on the top/bottom of each INPUT text field. So far, I have no luck to remove the extra margin on the top/bottom of text field.
