Going LCD is a no brainier.
No worries of burn in. LCD's have less power consumption. The matte finish on the LCD screen has no reflections, plasmas have glass screen. Plasmas also run hot so you'll likely notice the temperature of the room increase (which could be a good thing)
Only advantage Plasmas have is that they will have a better black, but most LCD's sold today are very close to the quality of Plasma black reproduction.
With either LCD or Plasma you decide to buy, make sure you stay with a 1080p TV. Most LCD's are 1080p but Plasmas are 720p or 1080p.
Your post is full of miss-leading information.
Plasmas have superior black levels.
LCDs produce pretty bad blacks that look grey in dark rooms. This is due to that dreaded backlight that is always on.
Plasmas are excellent for gaming.
I pay 3-6 hours straight on my 50" Samsung plasma after a 200 hour break-in period and I have SLIGHT image retention that usually goes away within 20 minutes.
Plasmas have a fast response rate and almost no image blur.
My LCD is horrible for watching sports and for fast paced motion. That is why I bought a plasma.
Plasmas display SD (Standard Def) a lot better than LCD's.
LCD's suck at upscaling content. SD looks a lot better on my 50" plasma than it does on my 32" LCD.
Plasmas don't produce as much heat as LCDs.
My plasma runs at 32C, my LCD runs at 77C... a HUGE difference!
I can touch my plasma with my hand and its fine. I cannot touch my LCD after being on for more than 45 mins.
I bet if I cracked an egg over my LCD, we wouldn't need a frying pan!
So.. GET A PLASMA!
You'll be glad you did. As long as you do proper break-in period. You will NEVER get burn in, and you will get minor IR (Image retention).
I used to be a LCD fan till I realized how much better Plasams are. I belive I am not biased as I have experienced both technologies and I strongly prefer one over the other.
Hope this helps.
