I have Ghost Armour on my Droid screen, and it has been working fine. It was installed professionally by a dude over @ Best Buy. My phone has worked flawlessly - no probs with the touch screen at all.
The Ghost Armour is effectively invisible on my Droid. I also have not had a single problem with the the film lifting up. About the only thing that has occurred is that a few very minor dings are visible in the Ghost Shield when I look at it from an angle (totally invisible when looking head-on). These probably occurred when I was carrying my Droid in my pocket, which means the screen was being protected.
The Best Buy Ghost Shield station had a small drying area, which had a small amount of heat and high speed fan to pull the moisture away from the devices within.
I was using my Droid approximately 1/2 hour after buying the installation. I was only told to avoid doing anything that would cause the Ghost Shield to lift up during the final curing process: Don't put it in any mounts or cases, don't put it in my pocket, etc. Just let it sit out in the open for approximately 24 hours, or until the minor ripples/bubbles disappeared.
So, for the few extra bucks, I would recommend going to a Best Buy and having it installed by the guy/gal who mans/womans the Ghost Shield station.
Also, I only purchased the Droid screen cover - not the full body cover. I believe that's the best way to go.
