Two issues, one of them straightforward, and the other... not so much. 
For reference, I'm connecting through an HDMI cable from my motherboard 
(onboard graphics), and running a 32bit color desktop.

First of all, it appears that my TV has a 17 bit DAC for color 
reproduction (6-6-5).  This can be verified by trying to "nudge" RGB 
colors by 1 unit; nudging either red or green produces a noticeable jump 
every fourth step (but no change in between), while nudging blue 
produces a jump every 8th step.

I'm actually switching to a better TV next week, but I don't know how to 
find the bit-depth it is capable of displaying.  I've tried various 
words and phrases on Google, but it appears this information is not 
readily available.  Does anyone have a suggestion for where I can find 
this information?

For reference, the TV I have now is a Sylvania LC320SS9-A, a 32" 720p 
set.  The TV I'm going to get is an LG 47LH30, a 47" 1080p set.

The second issue is harder to deal with.  I've been trying to calibrate 
the colors on the TV, and it doesn't seem possible to get a good setup 
for it.  No matter how I adjust things, some programs look good while 
others are either washed out or too dark.

I don't know how else to describe it, other than that there seems to be 
some fundamental differences in the color space between PCs and TVs that 
the traditional gamma / brightness / contrast settings can't account for.

Has anyone else here had experience using an HDTV as a monitor, and do 
you have any suggestions for the color calibration?
