From L2, which will be written up as part of another 117 related story today:
OV-104 (STS-117)/VAB HB-1
The Orbiter was powered up on Friday and snapshots were completed; next power up scheduled for tomorrow.
Hydraulic operations to preposition all aerosurfaces in support of engine removals were completed on Friday.
During a walkdown in preparation for engine removal, several scaffolding issues were noted. To ensure ET-124 repair efforts were not impacted, engine removal will be rescheduled to begin on April 24. This change in the schedule is not expected to impact the rollout date of May 6 nor the NET launch date of June 8.
SRB Solid State Video Recorder retest was completed on Friday.
SSME #2 will be swapped with OV-105.
Any word on why they are replacing SSME#2? 
Engine 2 on Atlantis needs to have its LPOTP (low pressure oxidizer turbo pump) replaced when they remove it for the Repliset contamination inspection. It is just logistically easier to swap the engine (when it comes out of Atlantis next week) for the engine on Endeavour. Before that engine is installed on Endeavour it will have a replacement LPOTP installed.
The LPOTP needs to be replaced because there is a potential corosion issue that is being investigated.

There is a lot of great information in these documents. The EVA and PDRS documents are especially interesting. Unfortunately the flight plan document dates from November 2006. That version of the flight plan does not include the changes made to support the P6 SAW retraction.

Here is this weeks Space Shuttle Status report from KSC PAO:
Mission: STS-117 - 21st International Space Station Flight (13A) -
S3/S4 Truss Segment Solar Arrays
Vehicle: Atlantis (OV-104)
Location: Vehicle Assembly Building
Launch Date: Targeted for June 8, 2007
Launch Pad: 39A
Crew: Sturckow, Archambault, Reilly, Swanson, Forrester and Olivas
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles
In high bay No. 1 of the Vehicle Assembly Building, technicians and
engineers continue repairing foam on the hail-damaged STS-117
external fuel tank, ET-124. The poured foam repairs are nearly
complete, and technicians are trimming and sanding repair sites.
Spray foam repairs are scheduled to begin next week. Due to the
amount of tank repair work remaining, the rollout of Atlantis to the
launch pad is now scheduled for May 12. This six-day change should
not affect the June 8 target launch date.
Preparations are complete for the removal of Atlantis' three main
engines to inspect for flow liner contamination. Engine removal is
scheduled to begin next week. This work can be accomplished within
the time frame of the tank repair.

During all this time that Atlantis has been in the VAB, has there been any work going on in the crew compartment?

Seems to me a good idea would be to use a constant slow flow of dry air (or dry N2) positive pressure purge throughout the payload bay, with the vents closed, to help prevent moisture buildup both within the bay and around the doors.
That said, I don't know what they're doing (or are actually able to do) for that while sitting parked in the VAB.

This isn't an remove and replace job. It's simply a remove and re-install job.

Oh thanks Dave. I too was getting a bit confused about the engine removal!
