Of the woods you mentioned, straight grained white oak or hard maple are two of my favorites. I haven't had as much success with red oak. Yes you can have a shelf on a board bow, but remember, every feature you add to your bow is another complication to deal with that increases the learning curve. It is not really necessary on traditional style bows as you can add a shelf and my primary focus on early bows would be tillering. As you get a few under your belt, you may want to tackle a cut in shelf which requires a thicker handle.
