Can anything be done about corruption?

Great, thanks everyone - now to persuade my Outremer govenors to change their build queues...

Forgot where I read it, but it might be that if you put spies into a settlement it could reduce corruption. Maybe somebody can confirm it.

IIRC the assassins guild line has a law PO bonus. (think its like 5% for level 2 and 10% for HQ or something like that)

Best method is to get a governor in there with lots of law bonuses. A good governor can do wonders for corruption. Of course baring the fact that he comes corrupt himself.
