Using Nero Vision Express, I've imported onto my hard drives some DVD
files I want to edit to remove unwanted material. The individual VOB
files now exist as a single Nero Showtime file.
Should I now convert that to AVI before using a program such as Adobe
Premiere 7 (I don't have that program yet, but a friend is letting me
use his program if I bring the material around on a DVD) to edit the
file? I've read that Nero Vision Express will let you export its
Showtime files as AVI files, but I can't see on my program how that
can be achieved.

This is because mpeg files are already highly compressed and
recompressing them with another editor introduces artifacts which
degrades the video. You will also find that either of these is easier
and more appropriate to your post than the Adobe product, which is
more suited for AVI/DV editing, imho.

AVI is a Microsoft wrapper that can contain mpeg files, DV files from
a camera, etc..., but one would need to know that the AVI editor would
not reencode a new mpeg from the mpeg in the AVI wrapper.

The two general editing formats that I am referring to here are:

Camera -> AVI/DV -> AVI Editor -> Encode as Mpeg -> Author -> DVD

or

DVD -> Mpeg -> Mpeg Editor -> Author -> DVD
