Muddling Around in Metaphysics

I have a massive paper due in philosophy class tomorrow morning. I have already resigned myself to being up half the night/all night working on it (although I am pretty proud of the progress I am making so far...nine pages is a decent amount to have done already), so I figured a short excursion into blogdom to clear my head was permissible. And I have been working on this things all day already anyway.
This twelve page paper is about Plato's metaphysics, specifically his theory of the Forms and how they and his dual universe (the visible world that we know, and the world of the Forms) relate. This really is a fascinating topic, although I very quickly become bogged down by all the philosophy words that I have to use over and over again, i.e., 'existence', 'knowledge', 'being', etc. We have gone over a lot of cool topics in class, but for some reason I cannot get this theory of the Forms out of my head. We went over this, what, four weeks ago, and I still think about it fairly often, trying to figure out in my head how it would work. I am really hung up on the idea of labeling, like, how we decide that a thing is a table and then therefore that it is participating in perfect Tableness. What I do not get is why we call it a table and not a platform, or a surface, or something like that. Do we just inherently know that it is supposed to be called a table, or is that just what we have always called it? Or does it even matter what human name we stick to it, because it just participates in a Form anyway?
Another thing, on this same line, that I have issues getting over is the idea of the human Form. Do I, as me, participate in perfect Humanness up there in Form-realm, or in perfect Jessieness? Does each individual have their own Form (thereby calling in the third man argument), or do we all partake of the same Form that is the perfect Human? And then, is it the perfect Bodyness or Soulness, or something else that is doing the participating? If it's the soul, then it would make more sense for each individual to have their own Form, because each soul, I believe, has more that is unique about it than each body does. But still, souls do share things in common with each other, but what is it really that makes up a soul, and how does that relate to what Form it correlates to?
Anyway, some things to think about. That rant is not really what I am writing my paper on, but it is just one of things my mind has been hung up on for the past few weeks and still has been unable to find any kind of satisfactory resolution. Admittedly, that was a very shallow explanation/description, but I have not the time to elaborate (a paper to write, don't ya know). Ask me about it sometime. T'will be fun.
