wp 2.0: wysiwyg .css / admin.css tweaking

dear readers!

just updated to wp 2.0 and got stuck in updating my backend. can´t find the place where to change the styles (fonts) within the nice build-in wysiwyg plug. i figured out that it shuold be connected somehow to editor_content.css, but my changes won´t have any effect..?

also i´m a little bit confused about some minor display errors in dbx-group element (discussion, password protect, titel…). my browser (FF 1.5) shows a thin border line left to the boxes headers. similar error (i suppose) in the iframe (upload-tab), here on the right hand side. in IE everything looks fine..? thought wp is optimized for FF not for IE?

by the way: does anyone know any alternative admin.css files for wp 2.0 yet?

thanks for all comments and, to the wp crew, for the great work you did creating this new ‘poem’ named wp 2.0!!!

best,
