I'm not a pc gamer, but I've been wanting to buy a "setup". I only game on consoles, and I'm tired of them. I heard that pc gaming is a lot better, but I wouldn't know where to start. I need advice on what I need to buy, prices, where to start.
As you can see I know nothing about the technical aspects lol
But, is it possible for me to just use a plasma as a monitor? 

I also wanna know if every game made for consoles (ps3, xbox, gamecube) has a pc version and how much (on average) do these games cost. 
I would like recommendations on monitors, desktops, accessories, etc....
Also, is it possible to use console controllers on a gaming pc?
And what's better in terms of repairs and maintenance, longevity, & performance. (gaming laptops or desktops?)

Any other advice or anything you could help me with would be greatly appreciated  

Thanks, Ash
