Nearly all residential conduit is made of plastic these days --
simply go to your nearest Home Depot/Lowes and wander back to the
electrical dept. You cut the stuff with a hack saw (or get the trick
tool if you are going to be making a lot of cuts) and glue it 
together with PVC cement. 
Be sure to leave a pull cord inside the long runs and don't ever
pull 120 volt a.c. down the pipe because the 60 cycle hum will
cause interference in unshielded cable.  It's been a while since
I last messed with PVC pipe but I think you can soften it with a
heavy duty hair dryer and create seamless bends with gentle 
enough arcs to ease cable pulls.

If you use 6" studs in a few critical walls (and the outside ones
to hold more insulation) you will have room to use 3" conduit without
any problems.

One last tip: keep the blue prints and clearly mark on them the
location of each piece of conduit (and what wires are inside.) Five
years from now you will be *very* happy you have that data.
