What makes a complete shop? There's no such thing!
What tools do you need? Whatever tools it takes you to make a complete knife...
Honestly, a list of tools could go on for pages when trying to "completely equip" a shop. A lot of it really just depends on what exactly you want to do. If you want to forge, start with a couple of hammers, an anvil, and a forge. You'll quickly realize what else you need as you start working on the projects that you want to work on: different tongs, drifts, hardie tools, etc...
If you want to focus on stock removal, it's the same idea. Make a couple of knives, and then ask yourself "what would make this easier, more efficient, more refined.... etc...."
Then of course there's the whole matter of deciding what type, brand, size, etc... of each tool you want to get. Some say to buy once, cry once... others buy what they can afford at the moment, use it to make money, and save up for the better tool.
Personally, I started out building my own grinder (NWGS), then I built a heat treating oven, and then I started making knives. If I needed another tool, I first asked myself if I could build it for cheaper, find it used, improvise something else, or live without it in lieu of something else I may have needed more.
