Reese, you really ought to take a closer look at the mod rewrite directives. A RewriteCond is a condition that must be verified (ie evaluate to TRUE) in order for the associated RewriteRule to be executed. So your
RewriteCond %{REQUEST_URI} ^/20\d+
will cause
RewriteRule (.*)(0[5-9]).html$ /20$2/$1$2.html [R=301,L]
to be applied ONLY if the URL request starts with /20 followed by at least one digit (/200, /2000, etc). This is clearly the opposite of what you want: you want the rewrite rule to be executed only if the URL request does NOT start with that string.
Also, why are you concerned with external links? External links, when clicked by user, will go to servers outside of your domain so your server will never see the request. The rewrite module works on the HTTP request to its server, not on the body (HTML) of request responses.
