The answer to your question is absolutely, there should be screws at the edge of the prop blade openings on the aft bulkhead.
With regards to the front bulkhead, it may or may not need one. It's been my experience that most aluminum spinners need a front bulkhead as well. I was quite surprised when I replaced the spinner on my Tomahawk with a new composite spinner, that the new STC'd spinner used a very rigid Carbon Fibre aft bulkhead and does not require a front bulkhead at all. The original aluminum spinner had both. What that implied to me, is that if the back bulkhead is rigid enough, then you may not necessarily need a front bulkhead. However, with your aluminum spinner, I would want one.
