when you move to CZ as a non czech speaking foreigner, i suggest to use
www.foreigners.cz
they sort out the things for you that you will never achieve without the knowledge of the czech language - or at least shorten the process immensely
i used them for my permanent residence and it cost me like 10 bucks - and for that they filled the application forms and went with me to the foreign police (where ironically not one single person speaks english)
