It would help to know which version of iTunes you are using and what platform(Windows or Mac) and OS.
The Owners Limewire tunes, I think, only appears when Limewire is switched on, and on iTunes 5.0 for mac it does not seem to appear atall. This list contains all the tunes you are sharing as far as I can make out, and is not able to be loaded onto iPod
If you have iTunes importing enabled in Limewire you might have an ordinary playlist lower down the iTunes list called LimeWire. This is an auto generated list in Mac at any rate which contains all the Limewire downloads. If this list does not appear you may need to create a list and drag all the tunes you want into it.
If you have automatic updating of iPod enabled, and there is room on your iPod for ALL your iTunes tunes, then provided your Limewire tunes are in iTunes they should be included in your update.
There are some who recomend manual updating of iPod , but I have never found this necessary, myself.
This gets a little awkward to explain, as 1. I'm not sure how this works with windows, and 2. It is not possible to see the iPod preferences unless iPod is plugged in!
There is a sticky which you should read if you haven't already (especially the posts by Lord of the Rings) :-

I hope this helps and I may add a bit when I have checked out what the iPod preferences are!
