Big Playoff game, need QB and RB help?

Alright, so I have Donovan McNabb vs Cle or Favre vs Buf, who would you start and why? Now this is the tricky part.I need to pick 2 RB's the league is none PPR. My RB's: Marshawn Lynch vs NYJ, Frank Gore vs MIA, Warrick Dunn vs ATL, Meweldi Moore vs BAL, Dominic Rhodes vs Det or Steve Slaton vs Ten. I have narrowed it down to Lynch, Gore (if he plays), Rhodes or Slaton. Which two would you pick and why?
