What the metatag= noindex does is make it so Google doesnt have a cached version. You know when you do a search at google, and all the listings have a "Cached" next to their listing. Well if you do the noindex meta tag, then it won't cache.
If you have a fairly decent rankig (i.e. top 20) then best bet is to leave it alone unless they are necessary changes. If you do have to change it, try to keep it minimal. But just keep an eye out when Google reindexes. Who knows, maybe the changes will give you a better ranking.
