Updating Blender 2.41 with plugins and scripts

I’m new at this so please bear with me.
Like others, I had problems with Blender 2.41’s ability to import .obj files, etc. Solutions were provided here in the plugins and scripts thread (I hope my terminology is correct.).
Is there a preferred or recommended method to load all the fixes at this site http://projects.blender.org/viewcvs/viewcvs.cgi/blender/release/scripts/?cvsroot=bf-blender into Blender scripts by replacing the old files with these updated ones without having to do each one individually?
