Where can I change page titles and custom fields layout?

I want to change name of pages Add Classified and Edit classified, because our site isn't in English. It doesn't work via Codestyling Localization and I can't find in which source file I can do this.

2) There is one more thing I want to change but can't find source file - custom fields layout od Add / Edit Classifies pages. It has table layout, I want just <p>. Where can I change this?
