If your tree had any lean to it, choose the staves from the top of the lean and the bottom of the lean as your favorites. They will show less warp as they dry.
After you get one of the staves down to near bow dimensions, you can clamp it to a 2X6 that you have cut a gentle reflex shape into. I clamp it then wrap it several times with packing tape at the tips and handle to hold it down. That way my clamps aren't out of commission for a month.
Do like Pat says with the rest. Or take them down one at a time while you are waiting.
Removing all the extra wood from a stave is the quickest and safest way to dry them. The trick is knowing what is the "extra wood". The ideal would be to get the bow completely cut out and into its final shape before drying. But we never know its final shape so we do the best we can. Wood checks and warps because of uneven drying. The less interior wood we have, the less uneven drying, the less warping and checking we have.
Have fun. Take pics. Post them. It's a rule here. At least I think it is
