I have a question about the Jewish Holy Books?

I know of the Tanakh and the Talmud. Are there other ones? The Tanakh is basically the Old Testament, right? And the Talmud is like commentary on the Tanakh, correct? Well, I'm looking into buying a copy of the Tanakh so that I can study more into the religion. Is there a certain version that you would recommend for someone coming from Christianity? Do you think that I should buy a copy of the Talmud when I buy the other one? If so, what's a good version of that one that you suggest? Thanks in advance.
