Looks like you're off to a great start. Of equal importance is actually where you set up all your new equipment. What kind of environment, i.e., a dedicated room, space in the garage, corner of the living room, etc. How about the bench--is it sturdy? Do you have a place to store powders, primers, bullets, brass, books, notes, tools, and stuff you haven't even thought of yet? Give careful thought to the layout of your work bench. I understand you're just getting started but make sure there's room for expansion. Don't crowd your bench--give yourself room to work.
If you don't have a suitable bench then build your own. I did and made it fairly large...36" wide by 5' long. It's almost too small now that I've added a progressive press to the original turret press, as well as a bunch of other gadgets and tools to make better reloads. The gist of all this is to give plenty of fore thought to your new project--how you do, what you do, where you do.
Cleaning dirty brass is a chore, at least for me. I usually de-prime then wash/soak the brass in a solution of Simple Green, lemon juice and water. Rinse well and allow to dry. Quite often the brass comes out looking quite spiffy. If it's rose colored then there's a bit too much lemon juice. It will turn back to normal after tumbling. I then tumble it in a RCBS Turbo something or other...don't remember the model using ground walnut shell. I may give it a second round with ground corn cob for a polished look. Everyone will have their own methods. I like mine.
I like Dillon's case lube for sizing brass. As mentioned in an earlier post, you don't need a lot and too much will gum up your die. I got a large foil baking pan from the grocery store to spray the lube onto the brass...just spray a bit, roll the brass around in the pan to insure good coverage and let it set for a few minutes.
I'm tired and it's late and I've rambled on enough. There's a lot of experience on this forum and I'm willing to bet someone will have the correct answers to your questions. Enjoy your new endeavor!
