Just to update everyone...
I never got a replacement LCD from the seller on ebay, and I shelved the project for a while. I could live with the cracked screen, and I was planning on getting an Incredible in August anyway.
But now that I'm not using the phone, I ate the cost and ordered another LCD+Digitizer combo to try and get this project done. I took it apart tonight, and while the main dis-assembly was very straightforward, the LCD and Digitizer are another story altogether.
In essence, you will have to replace the LCD, Digitizer, AND most likely the front faceplate. The order of attachment is Digitizer > LCD > Faceplate, and they are glued together, with the LCD stuck in between the Digitizer and Faceplate. This made it extremely difficult to take apart, and still keep the components intact. I ended up breaking my LCD and housing in the process, but I wasn't being particularly careful because I ordered a complete white housing replacement
Another issue will be the front buttons, as they're located on a flexible strip attached to the faceplate with glue, and I'm hesitant to remove it as I can't find any replacements online to order, and it seems very easy to break.
I will still be making a complete disassembly guide once I get the correct parts, but sadly I don't think there is any way to replace the LCD or Digitizer without replacing all three.
This is the housing I ordered:
