lefties: remlinger, rusch, mercker
righties: hawkins, farnsworth, leicester (or dempster or borowski
It's not bad. Plus, I suppose at least one of the starters will be pushed to the pen in the playoffs. More than sufficient. Was Florida's pen anything special last year? Nahhh. Lots of teams have bullpen issues. Oakland certainly does, but they still may overcome it.
Blue, as to (1), it's odd. I see people say that the Cubs suck against lefties. Now, you say a good righty holds them down. Well, it can't be both. We know this team can hit, and it's gotta either be against righties or lefties or both. Good righties can hit righties. The left/right thing is overrated unless you are lefty-dominant team with hitters that have trouble vs. those lefties.
As for taking a walk, that's true to an extent. But it's just one component. It's also why I like Walker in there at the top of the lineup, and why D. Lee would be my #2. The most patient hitters on the team.
Dusty? I dunno. I curse him all the time, but his teams have always performed best in the 2nd half of seasons and in general he's had good success. Not saying he's the best manager around, but he's definitely not the worst either.
