Well, I think that the first step is to decide why you're putting out a CD in the first place. Most self-produced CDs are sold (almost) exclusively by performers as a means of supplementing performance fees. It that's your bag, haveing a number of titles is probably your most important consideration (apart from giving a good pwerformance.)
    If you have ambitions about mass (or semi-mass) distribution, it's absolutely necessary for your CD (or you) to be heard as widely as possible. DJs, or a very busy tour schedule, are probably your best bet. And your chances of getting a reasonable amount of DJ play are slim, indeed.
    Do I sound negative? Yes indeed. I stock some excellent CDs from unknown performers. Sadly, unless my advice is solicited, unknowns don't get ordered.
