I'm pretty sure they're using the dye to discover the low spots and any cracks in the foam. You simply cover the area with dye, and sand away the red dye off the surface. The only spots left that have red color will be the low areas. This points out the areas that need repair. So, the red should be pretty much gone on the final tank.

I agree.
However, what was NOT on the site last week is what NASA has said to the press TODAY. The news has not gotten worse... it has not changed. But I think that is post-worthy, because it has been reported since the story here last week.

Snippet from L2:
OV-104 (STS-117)/VAB HB-1
The Mini Portable Purge Unit 2 (MPPU-2) continues to maintain orbiter moisture requirements with compressor 4 isolated. The crane crew is scheduled to support a swap to MPPU-1 tomorrow.
The SRB solid state video recorder R&R is currently scheduled for today and tomorrow contingent on access; a retest is scheduled for Thursday.
RH SRB igniter RTD (resistance temperature detector) R&R scheduled for today.
PR OEL-4-28-5135, LO2/LH2 Engine Cut-Off (ECO) sensor wiring routing violation was discovered; all four sensors are routed together and spot tied to each other. This item went to the ERB on 3/12. The position is to field route new wiring and separate all four sensors. This item went to OCCB yesterday.

"troubleshoot on the SRB hydraulic accumulator may require changeout" Quoted from L2.
If the SRB does require changeout, would that mean both would need to be changed? I remember seeing something about the propellant being produced in batches to ensure consistency between the left and right boosters. If so, or even if only one needs replacing, what work would this entail, how would it affect a target launch date, and would it affect the decision to repair or replace the tank (might as go all the way if they need to demate and wait for replacement SRB being my line of thought)

The accumulator mentioned is part of the TVC hydraulic hardware inside the aft skirt - no need to swap out an entire booster just for that.

We're not talking about the whole Solid Rocket Booster here, just a component of it.

When are they going to release the plan of repairing the tank? And is it still likely for a late April launch?

Smart Money is on early-mid May, but still too early to call.
Nothing is off the table yet!

A bit boring, but publically (not L2):
STS 117 / VAB HB1 / OV 104
ET engineering assessment and quality inspections in work
Orbiter TPS inspections and repairs in work
SRB op corrosion cleanup and RTD R&R is complete
SRB SSVR R&R in work

As per vast L2 information, NASA will stick with ET-124 for STS-117 (as opposed to moving to ET-117). Launch date appears to point to NET May 11, due to repair plan timescale and manifest options.
Article to follow this evening.

Update to nasa.gov Shuttle homepage. Doesnt appear to be much new info, but the main page now has an image of Atlantis surrounded by service platforms...
EDIT: Oh, and new images on
Kennedy Media Gallery

NASA.gov news can be a week behind, I would warn you. I know you are both new, but you'll learn.

You don't need L2, this open site is still the fastest. L2 is hardcore.

so with the tank being repaired in the VAB what are the repair techniques going to be to fix the tank? And with the repairs done in the VAB is a late April launch automatically out of the window and a May 11 launch is the only first option that is going to be available

Nothing has been ruled out yet. A late April launch is still on the table and no plans on what kind of repairs they will actually do has been decided on yet.
I can't afford L2.
