You will want some sort of case trimmer. Your cases will lengthen when you fire them. Then you'll need a tool to knock the burrs off of the inside and outside of the mouth of the case. You can get hand versions of these tools or motorized versions.
Like someone said above, a case tumbler to clean the cases after you shoot them is good. There are also various things to tumble the media out of them you can buy or make. Of course, you can always do that by hand.
It might have been easier to start with .40 S&W, but it will work out anyway.
I'd take it slow with the first batch and inspect early and often. It's one thing to wind up with one screwed up round. It's quite another to wind up with 200.
