First of all, I wouldn't recommend dropping your bench for extra SP and RP - you have a pretty good core, and you don't need to muck up your numbers for the production risks you would be taking on IMO.
Secondly, I think you should be looking to bench Murphy in favor of Holliday - you can drop O-Dawg to facilitate this - and then trying to sell high on Quentin/play up Young's potential, for an upgrade at 3B (I think this is your team's weakest point, and Reynolds is not helping you out at all lately)...
Hope this helps
