If you call the bowyer who made your bow, he will probably tell you what the recommended brace height should be. Otherwise, with the type recurve you are shooting, 8" might be a good place to start. Then try 8 1/4" and 8 1/2" and see what shoots best. The brace height is measured with a bow square from the string to the deepest part of the grip.
You want your fingers to reach the end of the glove, otherwise you won't get a clean release. The glove should fit as snugly as possible while still allowing you to hook your fingers.
First learn to draw the bow to full draw, then find an anchor. As Terry mentioned, "I think you are cheating yourself out of a bit more draw length." When you come to full draw, your finger may be further back than your current anchor tooth. Find something else to anchor on, like your thumb knuckle against your jawbone, for example. Something that is convenient when you come to full draw, not something that is arbitrary and forced.
