For one let Romo play this season without an extension and see how he performs. Although the line has its problems he makes his share of mistakes as well. If all fails then we move on from him and Garrett and go after a QB in either this years draft or next years.
Ratliff will play his final season this year and then I think he is gone. Signing Melton would make for a good 1-2 punch up the middle.
As far as Ware and Witten are concerned I want those 2 playing for us. You don't just cut a TE who broke the receiving record for a TE and a pass rusher who can produce a double digit sack season hobbled. Yet some will say keep Spencer. I say no, had he played the way he did from the get go he and Ware would have been a scary tandem. With that said we are getting rid of the right pass rusher in Spencer. We can't just cut and trade everyone. The cost of the cap hit and replacement makes absolutely no sense.
