From the looks of the tv, if beyond all hope, it is an HDTV, it's likely 720p, and being a very old tube tv, convergence is probably off, picture has degraded, and he is sure to be disappointed, trying to read text on it, as he said he wants to use it INSTEAD of a monitor. The best bet would be to just get a cheap (but full 1080p) LCD, the largest size you can afford. I did what he's trying to do years ago, running component from my eVGA 7600GT sli setup to a 27" Toshiba flat tube tv (excellent picture for DVD back then), and it was a crushing disappointment. 5 mins later, I disconnected it and never tried that again until I got an actual HDTV which I'm typing this on right now. Sfjkll, if you're truly serious about this, get an HDTV, or you're going to waste your money and be disappointed.
