Ask all of the question you feel you need to bro, that is what we are here for.
And to answer your question on the parts to fill a shell (I would rather answer here than on ebay lol), you are pretty close to the price at $140-$150 or so. As for the other part of your question, I will have to think abotu it. I would like to get what I'm asking, but if it doesn't sell, I will come down on it a little.
