Contrast is not exactly brightness, but rather the difference between dark and light areas. Take your TV for example, if you turn brightness up everything tends to be "lighter", and if you go too far, black will look somehow grey and white, well, really bright. If you turn up contrast what happens is that color gets more saturated, light colours become brighter and dark colours stay dark. Usually you want to strike a good balance between the two (500:1 or 600:1 are good contrasts).
the XXms is the pixel refresh rate. When you make a pixel certain colour in a LCD monitor, it takes a little bit of time when you deactivate it for the colour to fade. So, that's the time it takes for a pixel to change colours when ordered to do so (changing colours is slightly faster than turning it "off", but nevertheless, same principle). If the refresh rate is too high (25ms, nowadays, is bad) you will see "trailing" behind stuff that moves on the monitor. You should look for 16ms refresh rate minimum, and there're some monitors with 14ms refresh rate even. IMO, this is the most important aspect of the LCD, the faster it refreshes, the better the image will be.
