You might want to do that on wp_head and wp_footer actions.

That way you pretty much get everything between the body tags, which  
is all you care about anyway.

Though this seems like an awful lot of processing just to tag outbound  
links. Some of the ones you mentioned might be best served being done  
in the theme layer or hard coded.
