If you want Pages to be all in German the text as well as the Menus etc, drag Deutsch to the top of the list in:
Menu > System Preferences > Language & Text.
If you only want some text to be Spell Checked in German select the text:
Inspector > Text > More > Language > Deutsch
Language is like bold, color or the font, it is part of the text style.
