I think we need some cooperation to fix these complexed situation.

How about these steps?

1.define offset value for JOSM and Potlatch
offset: 30;-14 ?

diff(offset?): +0.00026, -0.00003
for example
(Bing)43.31880, 38.52070
(Ground)43.31906 , 38.52067

2.Re-align featured ways
-primary roads
-secondary roads
-some huge objects

3.Re-align all objects
I think JOSM would be useful to move objects at once.
(Though I'm not good at using JOSM)
