I used to practice kendo (not enough time right now in college), and just thought I'd (try) to provide some helpful advice.
first, shinai, hakama, and keikogi are NOT one size fits all. before buying anything, you've really got to do some research and know both what you need and what you're getting. For the shinai, a general guideline is that the handle should be about as long as the distance from your wrist to your elbow.
second, don't buy too much at once. all you need at first is the shinai (virtually everything is done with it). as you gain experience, go for a boken (wooden sword). they're pretty cheap (even less than a shinai), and will give you an idea of how much a real sword weighs, and behaves. You need this to perform the kata, which one must memorize in order to get any kind of rank in kendo. next, get the hakama and keikogi (they can be very expensive, so it is best to know for sure you're going to stick with it). Now comes the most expensive part: the bogu (armor). You cannot do any real sparring without it, and it'll cost you around $300 minimum. Furthermore, finding the correct size is even more critical than any of the other components, as not having the correct size helmet, or do (midsection armor) can lead to injury.
having a real sword is not necessary unless you intend to learn iaido (drawing and striking with a sword). furthermore, any other costume is not necessary if you're seriously going to practice kendo.
anyway, just thought I'd give you my perspective on things. basically, kendo can get expensive, so you'd better be sure you plan to stick with it before buying the more expensive stuff; further, it is imperative that you find the correct sized equipment for your individual frame.
hope this helps in some way.
