Can someone, perhaps from ULA, confirm if this mission will also be flown on an Atlas V 551 as opposed to a 541 or 531?

Yes, a 551.
They were all originally planned to be on the 531 configuration.  Late last year, -4 was changed from the 531 to the 551.  I think earlier in 2017, -5 and -6 were already baselined as 551's, as integration for those missions really hadn't begun yet. (maybe some LEI was done, not sure how much)

Where is the Atlas V and Centaur for the AEHF-6 launch?  The LVs for Solar Orbiter and OTV-6 have already been delivered.  Their launches bracket that of AEHF-6 in our most recent launch schedule.

OTV-6
Booster and upper stage have arrived at the Cape aboard the renamed R/S RocketShip (former Delta Mariner)

Quote
The stages were offloaded Oct. 7 and taken to the Atlas Spaceflight Operations Center to await further processing for their mission.

A United Launch Alliance (ULA) Centaur upper stage is offloaded from the RocketShip transport vessel at Cape Canaveral Air Force Station on Nov. 21, 2019 to undergo preparations to launch Solar Orbiter on its journey to study the Sun for the European Space Agency and NASA in 2020.

Presumbably that is one of the two C-5(M)C's modified to carry out-sized satellite cargos?

C-5M 70030 is not an C-5M-SCM.
5C-SCM serial 68-0213 = 5M-SCM 80213
5C-SCM serial 68-0216 = 5M-SCM 80216

Which airfield was this delivered to? SLF at KSC?  Skid Strip at CCAFS?

How many Atlas V/Centaurs can be held in the ASOC?

The Solar Orbiter LV is stacked at SLC-41.

The AEHF-6 LV is now in ASOC?

The OTV-6 LV is in ASOC?

Did the Solar Orbiter LV need to move out before this most recent delivery could move in?
