The two main resolutions to be interested about are 720p and 1080i. The "p" means progressive and "i" mean interlaced, in both resolutions every second has 60 (or 50 in Europe) frames of video.

Progressive resolution puts 60 complete frames on the screen each second. Interlaced resolution puts 30 frames of only odd lines and then 30 frames of only even lines up every second. Certain people find that the interlaced video causes flickering.

The 720p video resolution is 1280 X 720 pixels, which gives 921,600 total pixels and the 1080i video resolution is 1920 X 1080, which gives a vast 2,073,000 pixels.

The sound on HDTV will be heard in a superior way than it did on your analog tv, a few HDTV programs contain Dolby Digital 5.1 surround sound, but you will require the relevant speakers to be able to take advantage of the special sound.

You need to buy a new HDTV. Some HDTVs arrive with integral tuners, while others do not. The tuner transforms the signal into something that your TV can distinguish and use. HDTVs that do not come with a tuner are commonly called "HDTV Ready." An HDTV without a tuner is useless.
