I think PagedImagePlug should do the trick.

I don't know about your second question
- I do know that greenstone is excellent at automating these processes.

As an alternative solution; if you have professional-grade cataloguing
tools that support multiple theasauri then I suggest use them - and
then convert to Greenstone.
eg catalogue the items with your ILMS cataloguing module then import
the marc records into greenstone MARCPlug already is setup to support
dublin core - so I don't think it would take to much work.
BTW modern web-opacs make it easy to integrate greenstone with your
ILMS for a seamless patron experience. (your IT staff should find
greenstone a doddle to configure/administer)

One more thing - integrating the ILMS and Digital Repository System is
exactly what the National Library of Australia seem to to be doing
(http://www.nla.gov.au/dsp/) - just not with Greenstone. They built
their own Digital Object Repository.

I hope this helps.
