Display for FCP & CS5

I am expecting my new Mac Pro Tuesday. I have not gone with a new display yet, hopefully my 20" aluminum will work just fine till I make a choice on a new display. I like the new Apple display, just not the price tag, but I do like the look, just wish it had FireWire ports. If it's the best out there for the size I'm looking for then I will certainly take the dive.
I never worked on a glossy display with FCP or Photoshop, so I was curious how your videos and pictures look once you see them on your average LCD or plasama tv. I don't want my colors to be off much. Not sure if that's even an issue, just being cautious.
I certainly am going to need a display larger the 20", just works better for me and my eyes these days. I love my dads 27" iMac. 30" is my limit, no larger.
Its been over a decade since I looked for 3rd party displays and back then they were pretty much the same, plus I did no video or photo editing.
Here to ask what other displays are out there you guys like that are not as pricey as apple which have at least 2 USB ports and a iSight like camera.
My other concern is hook up. Just for example, does a Dell display have the same connection to the Mac? Or will I have to get a cable and have programs installed to have it supported? I have some time to go to local stores and take a look, I just prefer my fellow Mac peoples advice over a salesman cause I want honesty not some patting of sales numbers. If I do go 3rd party then its the first time ever, before my G5 I took whatever came in the PC bundle, when I got my G5 I picked up the 20", so this is one area I never jumped into. I do not do video work for a company, it's all me, given me only my experience which is obvioously limited. I used to run my own side business and now plan to restate it and of course I want my work to look great.
Thanks for any info, I'm very excited for the new machine to be here for Christmas.
Oh and lastly down the road I would like 2 displays. Again curious if the 20" I currently have will be fine or do they both have to be the same brand. Seems like 20" would be fine, but never did 2 monitors before, always wanted to though, just lacked the $$, why I want to get all info before I buy a new display. Thanks again.
