Sorry, I'm currently planning on learning Magyar (Hungarian) & I already have what I need for it (a book with grammar rules, spelling rules, pronuncation rules & most important of all, words (all I still need is enough time and willpower), but I'm afraid none of it is very useful when you want to have a sentence translated into Czech...
Maybe you could mail JSVOBODA & ask him for help? He's a Czech guy after all (although he has left freeones and I don't know if he'd like it if you bother him)......
