Mismatched Keywords, URLs and URL aliases

I have noted a couple issues on a site, when testing new features on a local install [marked as a support request, as I am unsure if some of these are by design]

1. A biblio keyword view (block) generates URLS like:

biblio/keyword/1

Biblio also has/creates a number of different URLs for the same keyword:

category/resources/esl
resources/publications.html/keyword/1

2. If I change the taxonomy alias, nothing changes (which I assume is due to biblio keywords being in the biblio table?). Is there a way to ensure consistency in the URLs?

3. A biblio entry tagged with the above keyword has different keywords listed — node metadata from taxonomy v keywords from biblio. See below link for live site.

This is user generated data, so I can't be certain how/where the different terms emerged from.
[on the test site, I have created node-biblio.tpl.php that removes $terms from the display as a workaround]

Any suggestions appreciated
