Social Bookmarking for new website

Hi all, I am new to all social bookmarking has to offer, so if you can explain all of the different things you can do for my site (and its articles), that would be great. E.g. show me a social bookmarking strategy. As I understand it, I need the following: 1) my website url submitted to many social websites. Should they be re-submitted once each month into the future? From different accounts? 2) Submit all of the articles in my site to Digg and similar aggregation sites (I have over 250 unique, quality articles). How many digg sites are there? 3) Stumble my site from different accounts, Digg my articles, etc. 4) Squidoo, etc? Please bid with a comprehensive strategy for my site. ** It must look natural to the search engines, e.g. deployed over an extended period of time. Thanks for your bids!! Dave
