Sure you can use less aged lime for undercoats.
(NOTE: get on our maillist (Only Fresco...) if you are not on it yet - soon we will offer lime putty for undercoats, we have tested it for 6 years and it sets faster and stronger,
also it is 1/2 the price of intonaco lime that we sell
at http://truefresco.com/frescoshoppe
HOWEVER this (new undercoats lime putty) is not to be used for intonaco (painting layer))

I did not understand this part. You want the wall to have no moisture - it will deteriorate the plaster if it had. You wet the wall before applying a new coat, otherwise you want to do everything possible to prevent moisture from staying in the wall.

You shuold be fine building the wall ontop of the existing wall. You must make sure that there is no leaks or water seepage in the "old" wall.
It is advised to offset fresco wall 1-1_1/2 inches away from the "old" wall
