What you are proposing sounds about right to me. If they are not
smooth on top, you are probably right that it does not help to put
sheetrock on top, so put plastic on top and then when they are dry
enough to hold their shape you should be able to remove the plastic
and have them upside down for the final drying without any covering.
Maybe cover for night and uncover during the day when you can check
them several times during the day for signs of warping. I doubt that
weights help much, but do it if you think it helps. I have a couple
"hints" pages that might help with drying and firing ideas.
