For extremely well-written hobbit-lore, I would highly recommend all of Baylor's work which can be found at the following site:
Mushrooms By Baylor
My personal favorite is the haircut scene from "The Care and Feeding of Hobbits", all of which is superbly written from Boromir's perspective; but that is a hard choice, and there are many other works there which I seriously enjoy. There is a new work underway about Pippin's recovery after Morannon which is excellent.
