Sheesh, thought you'd never come back.
Tim, if you've got a lot of rules to change, find a text editor that does Regular Expressions and feed it your htaccess file with the following:
# change . to \.
^(Redirect \d\d\d \S+?[^\\])\.
# now change Redirect to Rewrite
^Redirect(?:Match)? 301 /(.+)
RewriteRule $1 [R=301,L]
^Redirect(?:Match)? 410 /(.+)
RewriteRule $1 - [G]
These can safely be done as unsupervised global replaces-- but of course you'll make a copy of the htaccess first!
