I'm sure wonders make everybody empire wide happy for a specific number of turns, but their effect slowly collapses over time by about 5%.

I'm not totally sure if this is the case everywhere, but in most cases +1 of something typically means +5% to factor. This is true for generals, but I'm uncertain about the wonders.

I'm sure that internal trade is as profitable as external trade with other nations. This is one of the reasons the Roman civil war doesn't result in massive bankrupsy for all the Roman factions. Each good appears to have a specific taxation value which enters your coffers regardless of who it is sold or given to.
