I understand your reasoning, but you are on the wrong track to say the least. You do not want to plug audio from HT system into a TV. You want to plug all audio sources into the HT system and turn the speakers on the TV off. Your HT speakers will replace your TV speakers - its the whole point of having HT. All that being said if your TV/ HT system has HDMI then audio will go across that line.
TV speakers are pretty weak, on new flat panels they are even worse due to their small size and awkward positioning. A basic HT system is a 3.1 system meaning a center channel speaker to deliver dialogue and two stereo speakers, the .1 indicates the presence of a subwoofer for base. A 5.1 system add two rear speakers for surround sound and 7.1 adds two more. 5.1 is a pretty reasonable route to go. An even more simple solution would be a soundbar with a subwoofer (sound bars have small speakers and need a sub to complete the range of sound and you do not need a HT receiver. The first thing you need to do is look at your HT receiver manual and figure out your setup. There can be quite a few variables that can come into play.

You will probably need a mini plug to RCA adapter so that you can plug your audio into the line level input jacks on the back of your surround system. One thing you'll need to be aware of, is that the audio output of your .mp3 player may over drive the inputs. If that's the case, try to find an adapter that will reduce the volume from your .mp3 player to levels that will allow your sound system to handle the audio levels easier.
To convert a 1 line phone system into a 2 line phone system you will need a phone that has two input jacks and two separate phone lines coming into the building. Each phone line will be plugged into one of the input jacks and the phone will then be able to receive calls on either line.
