My TT Shiv Comp Rival should be arriving at my LBS by the end of February, if not sooner.
What should my upgrade path be? I'm looking for the most bang for the buck in the near term as well as a long-term strategy.

I have purchased the same bike and the upgrade/changes that I have planned are the following. Change the saddle to the specialized toupe that I currently ride, I am changing the aerobars to an integrated bar setup with drop, and I am changing the chainrings/cranks to 53/39. I am undecided on the exact bars and cranks at this point.
I also plan on putting a center pull brake on the front.

Interesting. Why a center pull break in front? Will you eventually move to SRAM Red components?
I want a center pull in the front to clean up the cable routing and to be a little more aero. I won't be moving to red as I just don't see the value.
I ordered a Shiv Comp as well, but I'm starting to think about the Elite/Pro. All the components on the Pro < the difference in cost? SRAM Red all around, Aero chainring, carbon handlebars, integrated handlebar/stem, lighter by a pound (or more? for climbing)... And then I wouldn't have to upgrade anything else unless I get an itch for Ultegra Di2 TT (when it comes out?).
Here's a comparison of some of the non-groupset-specific components of the various builds.
Which of these components is worth upgrading first? For example, what is the cost-benefit ratio of upgrading each of these components on the Comp Rival to match the corresponding components on the DI2?
Stem:
COMP: Specialized EliteSet, 3D forged alloy, 4-position adjustable, 4-bolt, 31.8mm clamp
EXPERT: New Specialized proSet 7075 w/6061 faceplate with cone head bolt and plastic clip, 12-degree, W/4-degree shim
PRO: New Specialized S-Works Shiv aero stem
DI2: Same as PRO
Handlebars:

EXPERT: Same as COMP
PRO: Specialized Carbon Aerobar
DI2: Same as PRO
Brake levers:
COMP: TRP TL720 Aero lever
EXPERT: TRP RL970 carbon Aero TT lever
PRO: Same as expert
DI2: Shimano Dura-Ace Di2 TT levers
Crankset:
COMP: FSA Gossamer BB30
EXPERT: FSA SL-K Light BB30 carbon
PRO: Specialized Pro FACT carbon
DI2: Same as PRO
Saddle:
COMP: Body Geometry Romin Evo Comp w/ hollow Cr-Mo rails

DI2: S-Works Turbo w/Blackbelt protection, 220 TPI, aramid bead, 700x23c
Inner tubes:

DI2: Turbo Ultralight, 80mm presta valve w/ talc, .6mm thick
This bike is on my short list. I was thinking of keeping it as is, apart from bars upgrade, and then swap the drivetrain to Ultegra Di2 if and when it is released.
