Thanks for that last post. And thanks to the contributor for this mod - it's pretty easy to use once you figure it out.

Something that would have helped me would be to add a few more helpful hints in the GB Config area of the Admin panel; it was confusing to me what a few of them were - especially what to put for output file name. Took me a while to figure out that that name referred to:
Register your bulk upload .xml file [ie - create your own file name for your data feed] using the same name in your Google Base Configuration at base.google.com

Also, it would have helped me to have it made clear in the instructions that the datafeed creation is under the Admin/Tools tab - I found it after a while, but had to hunt for it.

I didn't know in which folder the feed would be located either, since it doesn't appear until you submit the feed; and GoogleBase asks for that info in its schedular.
