For the first month we have planned to do around 20 bookmarking, 3 articles each to 15 article directories, 30 directory submissions (priority to niche based), business page listing in hot frog etc, 3 articles each submitted to 10 web 2.0 properties, 1 press release to 15 pres release sites, some Q&A links and few blog comments, 10 video submission and 1 guest blogging.
Scrap all of this and use the time to learn seo. These tactics may have worked 5 years ago, but you will mostly be wasting your time doing this. I advise totally against 'submitting 1 article to 15 press sites' or the articles. Learn about duplicate content.
1 high-quality, engaging article submitted on a relevant industry website will be worth way more than spun articles on low quality article directories that probably do not pass any value. Sorry the above strategy just seems weak and ineffective, you need to spend your time learning about seo and content strategies and SEOmoz beginners guide is a good place to start.
