The center tool is a brotpisker or Danish dough whisk. It's the best utensil around for mixing bread dough, muffin batter, cookie dough, cornbread, waffles---any time liquid and flour meet in a bowl. My mom got my dough whisk for a quarter at a rummage sale in 1979, and I've used it to mix up thousands of batches of bread dough. They're available online from several sources, including King Arthur Flour, Amazon, and Sur La Table. They come in two sizes (14" and 11") but I'd just get the larger one, unless you never mix anything but pancakes.
Can you be successful at baking without these specialized tools? Sure---thousands of generations of bakers did just fine with wooden spoons and a wood burning stove. But they can make your baking experience easier and more enjoyable, and the pleasure that comes from using a well-made tool makes me want to bake more often, and none of my brother monks ever complain about that!
