trailing "/" on 2.0

After much searching of newsgroups/websites/apache docs....

the end of my httpd.conf now looks like this:
=======================
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.+[^/])$ $1/ [R]

RewriteRule ^/~([^/]+)/?(.*) /u/$1/$2 [R]
RewriteRule ^/([uge])/([^/]+)$ /$1/$2/ [R]

RewriteEngine on
RewriteBase /
RewriteRule ^foo$ foo/ [R]
=======================

and of course, there's not a change in the server behavior after several
restarts.

but the one thing I noticed is that ALL of the documents that I pulled these
"solutions" were for apache 1.3 and nothing was available for 2.0.

Is the version difference a reason this isn't working?
Is there a resource outthere I just didn't find for 2.0 that addresses this?

Or is there a person able to guide through cleaning up these rules to make
them functional?
