the rock chucker is an awesome press, it is what I use. I am by no means an expert, but I am confident that I would never need another press after buying my rockchucker (I may get a progressive press eventually, but that is another matter).
I am in school for machining and have micrometers and calipers, I have found that you really don't need micrometers for any but the most precision loads. you are just fine with calipers.
My rockchucker came with a priming tool installed. it is not the best primer tool in the world, but it works. A scale is very important, I would recomend getting a digital, they are much faster if you are going to be loading pistol cartidges.
beyond that, there will be more people who can tell you more soon.
