iTunes Question

Ok, so I came by an iPod the other day and am starting to fill it up, and am finding iTunes horrible, slow and cumbersome.  But complaints aside--is there some way that I could find out exactly which mp3's from my library are on my iPod at the moment?  In a move of incredible stupidity, I imported some folders that had multiple copies of many of my mp3's (all id3'd identically! ><) so now my library is bloated with dupes.

I'd really prefer not to just delete at random, since that would cause sync problems if the copy I deleted happened to be the copy on my iPod and I'd have to redo hours of work picking and choosing music again...is there any reasonable way to do this, or am I fucked?

OP here, I don't hate Apple at all actually.  And iTunes DOES keep my music adaquately organized, but it also lags like crazy.  Now, I don't have crazy amounts of ram, but one would think that simply browsing a list of MP3's wouldn't be the most CPU-intensive operation.  My only beefs with it are as follows: iTunes is missing a few key common-sense features integral to truly anal sorting, it's not nearly as intuitive as other similar programs I've used over the years, and of course, the killer lag.
