it's fine to rotate those frame in. put them on either side of the brood for faster build out. i quit feeding a few weeks ago, but my hives are established and had store.
the only way to know if you are feeding to much or not enough is to look inside. we are having a nice spring flow, but there is no way to know what is going on in your neighborhood.
don't know if there are any local clubs, but call Ruhl beekeeping supply and ask them. if there is a club, they will probably know. also check the Oregon beekeepers association web site.
