Guys, guys, relax.
Have both of you tried simply going to the Limewire preferences at the top of the screen? 'Cause if you didn't then you should know that there is a selection there marked iTunes and when you click it, you get a box that you can tick which will enable iTunes support, meaning that whenever new mp3s are downloaded thru Lime they automatically are ipmorted to a new Limewire playlist in iTunes, from which, of course, you can export them to your iPod and stuff.
Unfortunately, this only works for future downloads and you're gonna have to import the previous downloads yourselves.
Now, if you've already done that and still the downloads won't go to the iTunes playlist, THEN you may have a problem.

P.S.:You should know that it has been reported that sometimes the "iTunes support" box ticks itself off. If you notice that yo' songs aren't being imported anymore then check the preferences again.
Oh and this is from an OSX 10.2.8 user with 3.6.15 or 3.8.5 Lime (both work this way)
