Michael Dindinger outlined some basics for researching your Czech ancestor, here. We followed up, with some Czech Ancestor Research videos, here. However, there is MUCH MORE than these. For one example, Facebook has many Czech Genealogy special interest groups. While I don't personally have any (known) Czech ancestry, you might want to look into Facebook. A search of "facebook czech genealogy" reveals the following:
Czech Genealogy
Czech Genealogy for Beginners
Czech Bohemian Ancestry/Genealogy
Czech Genealogy DNA
Czech Genealogy Services
and the list goes on. Alternately, search "facebook bohemia genealogy" or "facebook slovakia genealogy."
