When Lucas shot EpII, did he use any sort of anamorphic lenses to ensure that he was using all 1080 lines of res?------------------

No. All of the HD 24p productions released in 35mm scope ("Jackpot," "Session 9," "Star Wars: Episode II - Attack Of The Clones") have utilized spherical lenses.

What about Dancer in the Dark?

"Dancer In The Dark" wasn't an HD 24p production. I believe it was originated on DV. Someone else familiar with that production will have to chime in regarding the photography specifics.

There's apparently some issue with using anamorphic lenses with video cameras. Unlike film cameras, a high-end video camera contains an optical splitter to direct the image to three separate imaging devices (CCDs now, tubes in the past). Apparently there are problems with registering the images on the CCDs when using anamorphic lenses that Panavision couldn't solve.

Anamorphs and beam splitters seem to have problems togather as that is why they can't use an anamorph with the sodium backing travelling matte system

I'm not a lens or video camera designer, but I recall that the beamsplitter prism in video cameras that use 3 CCDs requires the use of TELECENTRIC lens designs. AFAIK, existing film camera lenses can NOT normally be used on 3-chip digital cameras that use a prism beamsplitter:
