A single stage Rock Chucker, a set of dies, a set of calipers, a scale and a load book is a fine starting point. I would recommend a vibratory brass cleaner and sieve as the next most important items. From that baseline, you can load pretty much anything you desire. I started with a used RCBS Partner press (single stage) and learned the fine art of weighing powder, adjusting dies, seating bullets and getting crimps just right for revolvers (roll) or semi-autos (taper). Once you master those basic skills, they transfer right to the progressive press devices. A cartridge gauge for the cartridge you're loading is a good check for proper crimp, OAL and proud primers. A bullet puller will eventually be needed. Nobody gets it perfect 100% of the time.

RCBS sells a great little starter kit that contains almost everything you mentioned. I keep threatening to go to a progressive but after watching my buddy cuss at his Dillon I still need convincing.
