For cheap home sites,
http://www.freeantennas.com/projects/template2/index.html and a
(semi-)flattened pringles do two things:-
1) kills the signal *behind* the AP meaning it doesn't extend equally
over next door :)
2) directs the signal towards your other wireless AP and/or laptops.
Over two floors, don't forget to tilt the antennas :P

7dB antennas are at least $60 each, so it's not the cheapest option.

IIRC Matt Kemner was a member of www.e3.com.au, so he should be a good
source of info should you want to do longer distance wireless.

My opinion is VoIP should only be run on wired connections or wireless
with decent (real) QoS. The latency comes from the encryption and error
correction from other power glitches/noise. Ethernet over Power has
*very* variable throughput. Halve whatever is on the box, and that's
been a realistic indication on the couple of sites I've used it (in that
sense, it's like wireless :P )

Had VoIP been mentioned, I wouldn't have recommended it :P
