Hi
I agree with the above, you run the risk of getting hit by Panda. If these pages are important to have live to help customers, then surely your priority should be to get good content on their to help your customers / potential customers. If they land on a low quality page with very little content, are they likely to stick around.
I wouldn't put any live until you have the content sorted. I would work out the priority and start there and once the content is good then put live.
There is probably a Panda update around the corner and you don't want to get hit with hit and then you are waiting for Google to release the next version to get out of it.
I wouldnt even run the risk of putting them live with noindex.
Unless of course as said above you have 100,000+ pages of amazing quality content then it probably wont affect you.
Thanks
Andy
