First question:Is taking the favor tile part of the building process of a temple?
Thus the town can just be built when the favor tile has already resolved. If you gain two favor tiles at the same time, they resolve at the same time (for being part of the temple building process).
Otherwise the town can be built BEFORE taking the favor tiles.
(But this is not the question here.)
Second question:
The town is built when conditions are being met. This is after the favor tile resolves. In my opinion, it cannot resolve "partly", even if "founding the town is no active procedure". (There were some hardcore gamers around me and they saw it the same way.)
Perhaps one of the game designers may help. :)
ps.:@Malte: Thank you for the link, but there are not just people speaking German here... ;)
