Running unbalanced audio - distance?

Having decided that I can't wait for the KAT5 switcher, I've decided
to go for an Extron MAV128 video/audio matrix switcher to form the
heart of my distribution system. This takes baseband composite video
and unbalanced line level audio (RCA connectors).

The questions are:

1) How far can I send unbalanced line level audio?
2) What cable is best (twin screened audio cable?) and what
difference does this make to distance and interference?
3) Is CT100 fine for composite video (15-30m)?
4) What connectors are best at the other end for both audio and
video (BNC, RCA etc - is there adifference in resistance, quality
etc)?

I could use KAT5 modules on each of the outputs of the switcher and
a receiver on the TV end but this would mean 7-8 transmitters and 7-
8 receivers = more expense + boxes (and PSU's) behind TV's that I
don't really want. If I can do it with cabling alone that would be
best.

Any thoughts?

Ta,

Paul.
