Funny enough, I got the basics up and going and... managed to break it again. Turns out if I install Avast! antivirus (which I've used for years), my computer absolutely will not boot windows. This time, at least, I had a system restore point (like it mattered this time anyways).
So, long story short, it'll probably be another day or two before I get everything up and running the way I like it and WoW installed again, especially since I'm probably going to sleep until I have to go to work. >_>
