Should I go after a big name 1B,RP, or what am I missing?

I am part of a 12 team HTH fantasy keeper league in which we will keep 2 batters and 2 pitchers each year.

Hitting stats are: R, H, HR, RBI, SB, TB, AVG, OBP, & SLG

Pitching stats are: W, L, CG, SV, K, HLD, ERA, WHIP, & QS

My team currently is:

C- Miguel Montero

1B- Lucas Duda

2B- Dan Uggla

SS- Asdrubal Cabrera

3B- David Wright

OF- Curtis Granderson

OF- Jacoby Ellsbury

OF- Melky Cabrera

Util- Derek Jeter

Util- Howie Kendrick

BN- Peter Bourjos

BN- Coco Crisp

BN/DL- Stephen Drew

Starting Pitchers: C.J. Wilson, Matt Harrison, Shaun Marcum, Johnny Cueto, Ivan Nova, Colby Lewis, Dan Hudson

DL- Chris Carpenter

Relief Pitchers: Joaquin Benoit, Fernando Rodney, Francisco Cordero, Kyle Farnsworth- DL

As of now, my keepers for next year will likely be Ellsbury, Granderson, C.J. Wilson, and Chris Carpenter

Now, we only have 2 DL spots on our roster, of which I am holding Carpenter and Farnsworth. I know I need at least 1 more RP for more saves, especially since Rodney will probably be switching off with Farnsworth once he comes off DL. I have Benoit and Cordero for holds, which I kind of feel like is a waste of a pitcher slot. Should I drop/trade one of them for someone to get me more saves? My starting rotation looks somewhat reliable, not overpowering and could likely use some work. When I look at my batters, I see a very good OF, Wright is solid at 3B (as long as he is healthy), and a decent SS platoon between jeter and cabrera. My biggest concern is at 1B however. I have kendrick as a util. and Duda slotted there now, which in week 1 was a good move, but I am wondering how Duda will hold up over the course of the year. So there you have it, where should I look to improve, who should I move, what would you do!? ANY help is greatly appreciated!
