it sounds like your well on your way.
Hope this helps. Lisa and I have just completed pretty much the same ride via the Stans, Russia and Mongolia and are posting the ride report here on adv.
Here's the thread http://www.advrider.com/forums/showthread.php?t=568229
We've included all the waypoints for the home-stays, guest houses, hostels, hotel and even wild camp spots. So i hope that may be of use to you. Thinking about it we also waypointed the various embassies and consulates where we obtained our visas.
There's a ton of more info on our site http://www.2ridetheworld.com

The stans are fantastic to ride and Tajikistan simply blew us away...incredible. You are going to have a wonderful time...enjoy.
All the best
