Actually with the after pics, it looks like light is leaking through every centimeter of every side now. And that's why you can't notice it, because the whole screen is bleeding. Also I wouldn't be surprised if dust starts to build up under the screen.

At an angle all LCD's look like that, they are lit from the sides. And making the foam uniform would not cause dust to get into the screen if you did it correctly as the LCD glass is perfectly flat to begin with and does not flex much, which causes light bleed to begin with when the foam gasket puts too much pressure on the glass in one spot.
OP did a good job and made plenty of warnings along the way. The logic and mechanics of the problem are sound and you should, as with anything you find on XDA, proceed at your own risk. I've done iPod repair for several years so Im not talking out my ass, they have had light bleed issues off and on as well. usually it was something being mal-formed pressing on the screen from the inside.
I'm wanting to know if there is a way to do less tear down to get the mid chassis out and access the LCD? In your teardown was it necessary to remove all the PCBs from the mid chassis to get it off the front panel? It wouldn't be to big of a deal if there was a simplified way to access the LCD only instead of doing a full tear down.
FYI my suggestions, when you do this, get a air ionizer and do it in a place with no carpet and wear an ESD strap to remove static electricity from your body, not so much to protect the PCBs but to keep dust from clinging to you and your tools due to "static cling". they also sell anti-static spray that will greatly reduce airborne dust particles in a given area. Great job OP.

Superglue a screwdriver tip into the stripped screw let it dry for a bit and turn I've done this a couple times it usually works

There are special drill bits named screw extractors ( http://www.amazon.com/gp/product/B0...=1789&creative=390957&creativeASIN=B001A4CWHO )for removing stripped screws and bolts. The screw extractor taps into the stripped screw which are used with a variable speed drill running in reverse at very very low speed or, better yet, use a manual tap handle. An alternative to the special drill bit is a reverse spiral drill bit which is meant to be used with a drill running in reverse. The drill bit has to be made of harder steel than the material being drilled so make sure it is titanium.
Here's some methods:

I just found this which may be the best tool for what you need to do:

I'm glad I came across this thread but not because my G2X has screen bleed. It took a tumble and the back case popped off and the camera lens landed right on a pebble and broke the lens. I used some angle tweezers to remove the pieces of glass and blew it out. The camera still works fine. Not sure if that lens served a purpose other than protection but I don't notice any difference. I think it might of had an anti-glare coating on it though. Anyways I figured the cameras were hard wired on to the board but I see from the OP's pics that it is detachable so I googled G2X camera and found a replacement on ebay for $8 and waiting for it to arrive. Doesn't look like I will have to dig to far into the phone to get to the camera so that's good. But if I need instructions on getting to it by George I know where to come to.

27Well I got Tired of the screen bleeding on my phone, so i disassembled it to see what was the problem.I noticed that there was a part of the dust filter surrounding the LCD, it was a little bumped up and when i would ever put pressure on that part of the screen there would be more screen bleeding(when it is assembled) so i scratched that part off and no more bleeding. sorry about my crappy camera...
