Remember: the port is not in any way complete and very very fresh, expect missing or non working features, there is no manual available and the installation procedure is not "official" yet.
About your two issues:
1) Install the fonts package, choose a font that includes cyrillic characters. Search a bit in the forums for more general information like this before.
2) Yes, it's known that there are still some quirks (I also knew about the set time screen), it's a new port...
3) Please, don't report every single thing here, do some searching before, be patient, wait for official support and the manual... give it some time especially for these small, not critical problems.
