On the topic of TV- you really dont need to spend that much for a really good monitor. Also, I recommend using two monitors.
32" is about the biggest you are going to want to look at, if its going on your desk. Bigger sounds nicer, but it really isnt, you will be swimming in the thing. 1080p on 32" is about the right size, big enough that its awesome, yet good enough res/size ratio that nothing looks pixellated, its all smooth.
If you want more screen real estate for coding, researching, or anything else where its nice to have tons of shit up to x-reference, just get a second monitor. Dual monitor is the way to go, and everyone who does any sort of real work on a PC needs it. I personally prefer a smaller second monitor, its a matter of taste.
Should you decide to go with 42" or larger, I HIGHLY recommend mounting it on a wall a ways away from you and using a second monitor on your desk as primary. Bigger isnt always better unless its also further away.
