How hard would it be to get ahold of these types of records?

Card Index of Citizens or Register of Citizens  Nuptial Protocols  Books of Banns  Books of Confrimees Parish Census Books  

I am looking for them in Rybnice and Lomnička (which is near the town of Plasy), Pláně (which is near Plasy as well).  Just trying to see what else is out there to look up that I haven't researched yet. 

Thanks.
