I think that you should use get_i18n_content instead of getPageContent, see here:
http://mvlcek.bplaced.net/get-simple/i18n:en/
in Language dependent Content -> Pages
As for the short text (NejnovějšàÄÂlánky), see (same link above):
Language dependent Content -> Conditions
(I forgot) ...or you could use get_i18n_component and create two (almost identical) sidebar components, one for each language.
PS I don't understand why the News Manager Addons functions didn't work for you in component. They should (it's how I use them). BTW you should add a ; before the closing ?>
