Some older TV’s actually use to have speaker connection jacks on the back of tv that allowed you to connect standard stereo speakers to them.
New TV’s however have the analog Red/White composite connections, which bring up a problem for you because then you need an amplifier. What I did to solve this was I used a set of computer stereo speakers (Klipsch THX ProMedia :-P) which have their own amplifier and work just great with an easy mini->rca adapter
To your last question, NO, you cannot use your TV’s volume control for the second scenario i described above. This is the part that’s annoying, and all the more reason to use an AVR. Unless you’re using an HTPC, in which case the Mute/volume buttons for the system (not the TV) will work on your speakers.
