Bill-you're going to have to be Father Merrin, given your age.
I'm thinking that Wood, when he returns (and he will) should revert to playing C, with Incognito and Levitre the starting guards. It'll mean re-signing the volatile tattooed one, but it's a risk I'd take. Hangartner can be the principal backup interior OLineman.
Schobel beat his man enough today to show he's recovered, which was a huge if entering the season. Hopefully the off-season will provide him sufficient rest, but they'll need to get someone who can not only be sold to RW and the fans, but the players as well.
The Bills will need to get creative to find their next QB, with the FA options being underwhelming and the draft not featuring someone (at this point) I'd take with the 7th-10th pick.
