quality difference?

I think it's too late for you to IVTC your source AVS files in Premiere, since you probably edited on a 29.97fps timebase. So if you suddenly changed your timebase and source frame rate, you may notice synch issues with footage or effects.

1)It's best to IVTC before you start editing.

2)I either use a software mjpeg codec or huffYUV.

3)If you want to use the realtime features of a DV500, then you would need to convert the source to the DV format. I believe ErMaC, may have done this and then just de-interlaced after he was finished.

4)Anime is done @ 24fps(or 23.976 NTSC). If you want it to look it's best on a computer, then you want 23.976. If you want it for TV display, then you would be best to edit @ 29.97. Exception would be if you exported it to a DVD/SVCD or VCD. You can use FILM rates with those.

5)I am not sure how you would telecine your video back to 29.97 from 23.976. If you need it @ 29.97, then I would just edit it at 29.97

Klinky, look in the Adv. AVS section of AD and ErMaC's guide...at the bottom, there's an AVISynth script for telecining.

Yes, agreed if it is only to be done using no editing hardware and then rendered for computer viewing only (non-interlaced)

Yes, same here, this also gives me the choice on keeping things interlaced at full frames (29.97) and being able to output DV tape or another video format for TV broadcast

yes, and agreed as well. My point I guess is to make the video versitle enough that it can be shown in NTSC at at con lets say as well as for digital distribution. I tend to see quite a few videos at contests that have just don't flow smoothly during a pan (jerk slightly) It's comes down to having being able to edit with the equipment on hand as well as having it perfect for a TV / video display as well as a digital file on a computer....
