If you get visits from search engines to those pages it would be crazy to 
get rid of those links.  I would however install the new pages without the 
query string and try to get as high as possible with as many SE's as 
possible.  Once those new links do their work, you have an alternative and 
you can get rid of the old links if you want.
Most major SE's don't like different links to the same page, so it is 
actually an advantage of having only one good link to a page.  Then again, 
it's only a disadvantage if you get caught, so you can keep the old link 
with some spam risk involved.

Robots will revisit your site after a certain time.  Most have an interval 
of about 1 month.  If it gets a 404 page not found it will erase that page 
from the index.  That will get rid of the old links automatically.  You can 
get rid of them manually by resubmitting them, but that's a lot of 
work.  If they find the new links, they will index the pages.  If some 
pages are in a search engine, it will get out and get the new pages 
automatically.

Keeping track of the logs is *always* a good idea!

BTW:  Don't confuse Search Engines with directories.  Search Engines use a 
robot to index the content of your site.  Directories like Yahoo en Open 
Directory (dmoz.com) have humans look at the site and quote it.  A clear, 
good content is all you can do for these guys.
