No idea whether this is all the problem. Try and check the 'Realtime'
checkbox in the qjackctl settings-window and put the 'priority' value to
something like 70 - dunno why realtime is allways deactivated by default
- even in audio-distros.
make sure the -R and -P options appear in the output:

/usr/bin/jackd -R -P70 -u -dalsa -dhw:0 -r44100 -p64 -n2

There is a reasonably recend howto for building low-latency kernels on
debian here:

it worked for me with a 2.6.21 kernel just yesterday, but i recommend
audio distros - lost so much time trying to do things i don't know
anything about.
Another helpful source of information is this:
