welcome to the DfM project
About Zdenek's "Wiktionary dictionary": could you try to contact Zdenek himself ? He may be able to create an updated version, or maybe he can provide you with the needed dictionary data files.
The information at "Setting up a New Dictionary" should provide everything that is needed for a novice to set up a dictionary (if there is a lack of information, please let us know). However, dictionary specific information (such as Zdenek's Wiktionary dictionary) must be obtained from the authors of the dictonary.
Anyway, just let us know if you have any specific question, we will try to help.
