Header and Navigation Spacing issues

Hi,
Maybe you help me with the best way to achieve what I need. I am hoping to have a set height of the header. (I would use the shrink animation if I could get it to work) I used the code on this page to help with a jumping section problem.
#header, #header-wrap, #logo img { height: 100px !important; }

I am combining the menu animation look from the ecommerce with the regular template. Not sure if that is throwing anything off.

I have also used the code from this page to help with height. I am changing the custom value to 90. Do I need to change that everywhere there is a 70?

So it mostly works but can you tell me how to keep the bottom 1px line on the home page header section

and also how to line up the drop down menu with the top of the page-title section on this page:

Thanks for any tips.

Ok, I got it to look mostly how I want. There still seems to be a little jump of the content up the page. Like a 1px jump. I see it happens on the your web version of Canvas too. Any fix for that?

Thanks.

Works great! Thanks!
