Hi
Here's my first go at answering a long post - here goes...
To answer your questions in turn:

line?

Your DSL device (modem or router) can cope with the voice signals just fine.
It is each phone or other non-DSL device that needs to have a filter to
prevent interference on the phone line and to prevent disconnections of your
DSL service. The easiest (and cheapest) way to do it is to fit a filter at
the master socket where the phone line enters the house first, put all your
non-DSL devices on the "Phone" side of the filter and your DSL device on the
"Modem" side of the filter. This means that every non-DSL device in the
house would be filtered. If you have extension(s) wired into the linebox,
this will mean getting a linebox type filter. If this is impracticable, then
the best solution is to fit a filter at every phone point where there is a
non-DSL device present.
Note that your DSL device will have an American style phone plug so if
you're plugging it into a normal BT type phone extension with no filter,
you'll either need to change the modem cable on it for a similar telephone
modem cable or buy a US-UK phone plug adaptor.

If you buy an ADSL router that allows more than one PC to be connected to it
then, with the correct network wiring, all you will need to leave on is your
router. If the router comes with a built in modem then you will need no
modems at all. The cabling that you will need are 2xRJ45 patch cables that
are long enough to go from your router to each PC. If you set up each PC
with reasonably secure measure (not allowing file sharing for instance) then
neither of you will be able to access each others files. I shall leave the
recommendation of routers to more knowledgable members of the group.

A line test is a check performed by BT to see if your line has the correct
tolerances to enable ADSL to work effectively on it. The standard test we
all hear about is the whoosh test where attenuation is measured and this
must be below a certain figure (62dB?) to enable ADSL to work reliably. The
reasons you may fail a line test include poor line condition, too many
joints in the line where water has been allowed to get in and damage the
line or simply being too far from the exchange. Just because BT broadband is
available at your exchange doesn't mean you will necessarily get it.

Plain Old Telephone System - in other words non-Home Highway enabled,
standard phone lines.
