1. You didn't answer this question. Will all or most bookmarks be guaranteed to be indexed if I check a week later? Not....."you gets lots of indexing through bookmarks". That doesn't tell me anything.
I can't give you any guarantee for the thing which is not in my hand. We use high quality and PR sites for good indexing. Good contents help alot in indexing and if your domain is google friendly then indexing will be quick. Indexing ratio can't be same for all websites.
