Leave the NOINDEX on each page, and get rid of the block in robots.txt, so Google can see the NOINDEX.
(You do realize that this will also take you out of Bing and Yahoo)
Good point, netmeg!
To remove pages from google index only, use meta name="googlebot" instead of meta name="robots"
Directing a robots meta tag specifically at Googlebot
To provide instruction for all search engines, set the meta name to "ROBOTS". To provide instruction for only Googlebot, set the meta name to "GOOGLEBOT".
