I own a PN58C8000 as of Nov 30Th 2010 and also intend to use the TV as a PC monitor. In an earlier post someone was warning me off, basically stating that IR (Image Retention) from the PC's menus would be too distracting for everyday use. I have not had these IR issues with my very limit PC monitor trails.
For 7yrs I used a 57" Rear projector HDTV as an everyday computer monitor and HDPC. There was never any burn-in with that HDTV and I used it for more hours as a PC monitor (programming) than as a HDTV for entertainment.
You asked: How does the PC image quality look when displayed on this TV..? Is it sharp & crisp or dull & blurry..?
Answer: I have the PN58C8000 attached to my PC via a DVI<->HDMI cable (attached to the TV's HDMI#1 connector). Resolution of 1920x1080p at 60Hz and it is crystal clear. Far superior to the rear projector HDTV which was only capable of 1920x1080i at 30Hz (component connected).
You asked: Does this TV have 1:1 Pixel matching..?
Answer: Yes the feature is called "Screen fit" but you cannot use it when attached via a DVI<->HDMI capable. You only get the 16:9 and 4:3 screen options. The good news is that 16:9 has no over scan so you get the 1:1 Pixel matching. I verified this using a 1920x1080 test image made specifically to check for over scan.
You asked: What kinda precautions would be necessary to prevent IR when using this TV as a PC monitor..?
Answer: I take several precautions.
1) Use burn-in slides for at least 100+ hours. My #1 worry with a plasma is burn-in. I am currently running burn-in slides to try to protect against burn-in due to PC monitor use. By Dec 7Th I will have achieved 100+ hours of burn-in time and will start using it as an everyday computer monitor. Beware that my answers to your questions are premature to whether long term use will cause burn-in/IR issues or not. Also some of my precautions are based solely my success with a Rear-projector HDTV.

2) Use dark/black computer themes (see attached images). I also recommend dark themes to reduce eye strain. I even use custom override Web page colors in my browser. Firefox has a plug-in called "ToggleUseDocColors" to toggle between your override colors and the Web page's intended colors.
3) Use two customized HDTV screen configurations:
a) "Movie" is used when I am playing video content from my HDPC software. These settings try to match what I have set for viewing TV from cable. I altered the default "Movie" settings to match the CNET settings that I like for Cable TV. Then I made additional changes as those settings are great for Cable TV but were too saturated for the PC's input. Note when attached with a DVI<->HDMI cable some of the settings are greyed out so you cannot exactly match the CNET settings. http://forums.cnet.com/7723-19410_102-500232.html
b) "Standard" is used when TV is acting as a PC monitor. I significantly lowered "Cell light(10)", "Contrast(53)" and "Brightness(25)". Also turned on the "Pixel Shift" feature (4 horizontal and 4 vertical every 10 min).
c) With the TV remote press "Tools" and you can switch between the two settings in 4 key strokes. Switching between screen configurations is very easy.
d) I used the AVS HD 709 calibration MPG videos and instructions but still made adjustments as I felt the PC images where still a little saturated. http://www.avsforum.com/avs-vb/showthread.php?t=948496
4) When a PC attached via a DVI<->HDMI cable is powered up you will not see the BIOS boot up or any screens less than 1920x1080, so I am also attaching a VGA cable to the PC VGA input of the TV. I have not done this yet but I expect that at some time I will need to see and change BIOS settings or see a boot up error which displays before the 1920x1080 signal is generated. Luckily my graphics card has two DVI connections.
5) I intend to regularly use the TV's built in wipe function to clear up any IR images. I do not know how regularly or for how long.
a) Hardware: Intel Quad core, and an old NVidia 8600 GTS
b) OS: Ubuntu 10.10, VDPAU graphics driver v256.x
c) HDPC: Mythtv 0.24 (Mythbuntu debs) with a Hauppauge HD-PVR for Network TV recordings.'
NOTE: These images being compressed jpgs make any text appear blurry. This is not the case with the actual display which is sharp and clear.
