What are you asking? Are you trying to set up a new Lee 1000 for 9mm, or to set up for 9mm and .45 ACP?
The two cartridges use different shell plates. I don't have the Lee numbers memorized, but if you have checked the table, then that is the right number for 9mm.
The trick is the primer size. The 9mm uses a small primer and the .45 ACP a large. The press, when it comes, is set up for either small or large. Then all you need is the shell plate and the dies.
You have to buy the whole shell plate carrier to switch from one primer size to the other.
As for case feeder, I have never used one and cannot advise.
