It appears that Jason Marquis will be used out of the bullpen during the first three games, meaning that the Rockies seem to be planning to have Jimenez go in game 4 on short rest and Cook in game 5 on regular rest. The possibility still remains that Marquis could start game 4, though no decision has been made on that. Likely if the Rockies are up 2-1 Marquis would start and if they are down 2-1 Jimenez would go.
Jim Tracy on Marquis:
"I think the first two-thirds of the season were exceptional," Tracy said. "Right now he's not throwing the ball quite in the same manner. And to ignore a guy that has thrown the ball as well as Jason Hammel has thrown it since the All-Star break, I really feel is doing ourselves a disservice."
According to the Denver Post, here's the playoff bullpen:
Belisle basically replaced De La Rosa on the roster. The Rockies have two lefties in the pen to help with the Phillies' Ryan Howard in particular.
From the same link, here's the Game 1 Lineup and bench:
Game 1 Lineup:
CF Dexter Fowler
LF Carlos Gonzalez
1B Todd Helton
SS Troy Tulowitzki
3B Garrett Atkins
C Yorvit Torrealba
RF Brad Hawpe
2B Clint Barmes
RHP Ubaldo Jimenez
This is pretty much what I figured the lineup would be for Game 1, with Atkins and Torrealba starting. I'm pleasantly surprised to see that CarGo will make the start in lieu of Ryan Spilborghs, though I believe that the Rockies are better suited with Gonzalez in the leadoff position rather than in the two hole.
EY2 has taken Quintanilla's bench spot while Giambi slides in as the extra position player.

UPDATE: Tracy Ringolsby adds his thoughts on the roster and mentions that Jose Contreras is also a viable option for the starter of Game 4.
