As for dead pixels, contacting Nokia authorized repair shop or Nokia Care is probably best. I don't think several dead pixels scattered across the screen is acceptable.

There is a bug in the screen calibration program atleast in PR1.0 that makes the edges inaccurate. The tscalib program is opensource and on gitorious, I downloaded and compiled it a few months ago when I couldn't get the screen calibrated properly. The gitorious version worked perfectly for me... I hope the new version was included in the 1.1 update...
