Hi Wes,
You can simply make one account on
Google Webmaster Central and block all unwanted URL's that you don't wish to be indexed. Google Webmasters section has another feature through which you can tell them which URL should be considered main URL of your domain and what others should be ignored.
I guess this should be the best solution for your concerns as 20 different will say 50 different things about Google indexing policies and it would be much better to trust tools given by google itself
