As my system has become more lived in I've noticed the time taken to
update the cache at the end of an emerge --sync is getting slower and
slower. The system will hang around 50% for a long time and thrash the
crap out of the disks.
Is this just usual behaviour for portage? Is there anyway to flush the
cache files and start again with a clean emerge --sync?

Well, you could try this:
http://gentoo-wiki.com/TIP_speed_up_portage_with_cdb
Several people here (including me) are using this without any bad effects.
You might also consider putting /usr/portage on it's own filesystem.
That would keep the disk accessed confined to a small portion of the
disk. The size should be 1-3G depending upon whether you keep distfiles
and packages on the same filesystem or not.

I noticed this broke after the recent Python upgrade - I had to remove the
module to run emerge.

Yes, but all you need to do is (as the python update ebuild reported but many
of us missed) run python-updater and it would have resolved the issue.
It was due to relocation of the libraries for py 2.4 vs 2.3
Run python-updater and then restore the cdb module.

I do have portage on the separate partition, but this caching process is
_DAMN_ slow. I remember times when it was really, really fast. WTF?
