More for your second question. Given the effects of drag, 40 degrees will actually give you more range than 45.
I have a spreadsheet that shows many options for the drag-less case, and someone else has a nice one that includes drag, but doesn't generate the other data.
Estimate your initial velocity, and start at short rage. be sure to put in the height of your shooter off the ground (for mine anyway). You might be surprised at what angles come out.
