GBL is by far most desirable index and very hard to get as Google is very sensitive and has trained nose to spam. When MSN/Live and Yahoo index backlinks coming from blog comments and social network sites, again Googel is clearly ignoring all that "spam"-like linking attempts.

GIP in general is giving some idea, how massive the site is and is it all indexed by Google. In general, bigger sites are getting better results ang higher PR's.
GSR is just a nice number, how many occurencies of Your site Google finds in the world. But GSR in nothing more than for ego tripping. Here You see all blog spam etc, what is not accepted as backlink.
