Not really the answer you want, but some ideas about it:

1) sed is fine, but have a look at
   filename=`echo $filename | tr -d \'\"\)\(\:\,\?\!\/\-`
   filename=`echo $filename | tr [:blank:] _`
   filename=`echo $filename | tr 'A-Z' 'a-z'`

2) I'm afraid you have to use mv for that

3) for a similar purpose I use procmail:
   :0 c
   * ^From:.*specialemailadr...@Iknowit.com
   |munpack -C $HOME/attachments && \
   chmod 755 $HOME/attachments/*.* && \
   rm $HOME/attachments/*.desc

   not exactly what you need, but might be an idea
   (this one was to save daily messages from one particular sender)
   
4) you probably know antiword with an autoview setting and the
   appropriate $HOME/.mailcap entry??
