If your surrounds are dipole speakers, then keep them where they are: directly to the sides of the listening area.
For regular monopole speakers, I would go with option 1. This should strike a good compromise between rear and side coverage in the surround field. Too far back (option 2) and you won't get any side wall imaging. To much to the sides and you'll end up with a sonic hole behind you. Somewhere around option 1 seems to be the right balance between side and rear coverage.
Good Luck,
Sanjay
