I still dont have Throne of Bhaal so i dont know about that thing. About the golden pantaloons and their use in BG1:

- You can:
a.- Identify them and give them back to the nobleman to get some xp
b.- Keep them. Later, in Baldurs Gate city, in the 2nd floor of the Splurging Sturgeon there is a guy who has some silly conversation (talking about the "trade", the dialogue has some very weird lines). If you talk to him and you dont have the pantaloons, nothing will happen. If you have them, heŽll take them and leave. You dont get any xp, its just a silly "quest" i think. But now that you mention that stuff Larry, i wonder if giving the pantaloons to this guy will have any effect on that armor thing
