[LAU] Jack vs Jack2, PulseAudio, Speech, Commandline!

Hi all.  I hope this hasn't already been covered, but I've been searching the internet and can't find answers yet.

I'm running Ubuntu 12.10 which came with PulseAudio.  I chose Jack2 as I have a newer system, I believe with multi-processor support, and I understood it might cooperate with PulseAudio better.  I use braille and speech for the screen reader, which is currently routed through PulseAudio.  And I want to use Jack through the command line rather than through Qjackctl gui.  I used to do this on my older Ubuntu system with Jack1, but things have changed quite a bit since then.  Jack2, Jackdbus, and module-jackdbus-detect seem to be working.  PulseAudio seems to be re-routing.  I don't have Jack running at startup, as I always used to start it manually, and so I could re-start it when necessary.  I currently start it with "jack_control start".  When I do, "jack_lsp" shows jack ports, but my old friend jackctl.py won't show any ports or make connections.  Running "jackd" as I used to seems to generate errors about not being able to start the server.  I don't have specifics in front of me, but I can come back with them if it helps.  I used to use ~/bin/j.ctl to start jack with the appropriate parameters I believe from ~.jackrc, but that looks as if it relies on something like jack.ctl which no longer exists.  

So after all the details here, I'm wondering if I should have gone with Jack1 instead, and found some way of doing without PulseAudio, or if my current Jack2 needs to run without Dbus support, and whether I need a newer jackctl.py if one exists?  Or are there other things I should be doing?  I'm sorry, but I feel just a little lost here.  I know just enough to be dangerous, but not quite enough to know how to fix it.  

Thanks for any help.  I'm sorry to be so long winded, but I thought the details might be necessary to know why I'm doing what I'm doing.  Any suggestions would be greatly appreciated.  Thank you again very much.

Kevin
