The rotate buildings mod is likely to be either a new file called game(x).cfg or a new proto(x).xmb file. If the former - copy it to your AoM/startup folder, if the latter put it in your AoM/data folder.
If Taunts mean the same as Chats, these are stored in a file called predefinedchats.xmb (the mod could be in .xml format, as the game recompiles any .xml's in the data folder on start up) and this should go into your AoM/data folder.
.... and I think to myself; what a wonderful world ... yeh!!!
