When will the new SMEs be installed?
This isn't an remove and replace job. It's simply a remove and re-install job.
I thought one of the three (number 2?) was being R&R'd.

No the change in the SSME inspection timeline caused them to opt for replacing the LPOTP on SSME 2 and then reinstalling it on Atlantis.
Engine 2 comes out first and heads to the engine shop then by the time the complete the SSME/MPS inspections on 1 and 3 they will have engine 2 ready to go back in.

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.

What changed?
The engine removals were deferred until after the "low-clearance" scaffolding around the tank can be removed. In the meantime, Endeavour's engines are either all reinstalled or will be soon. Before, both sets of the engines were going to be out in the approximately the same timeframe; with the engine removals from Atlantis deferred, that may have eliminated whatever potential schedule "gain" there was to be had from grabbing Endeavour's #2 engine for Atlantis.

They've considered it. No decision as of yet.

A direct quote from an e-mail one of my buddies at JSC sent me yesterday:
>>...we're tossing all kinds of stuff off that flight to make room for Clay Anderson, who looks like he's advancing one flight to get back in synch with the rest of his expedition. Quite a scramble!<<

Expedition 15 looks like the only one where every crew member is being switched around.

SSME removal delayed to Sunday.
If engine removal gets delayed too much longer, to the point of affecting the overall schedule, they could decide to do it on the pad in parallel with other pad processing.

Can they do that while at the pad? I mean I've never heard of it being done before.

They have formally approved the ISS crewmember swap for 117. Will this significantly increase the workload for the 117 crew?

So these delays are probably because the ET repairs are taking longer and they can't move the scaffolding?

Yes. Currently looking at scaffolding tear-down on Sunday, starting with SSME#2 removal on Monday.

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, Olivas and
Anderson
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. Spray foam repairs are scheduled to begin
Monday. Workers have begun disassembling the special scaffolding
built for the foam repair work, to allow for the removal next week of
Atlantis' three main engines to inspect for flow liner contamination.
