Ideas about SEO

Well recently i started a blog in a nice niche, eventough idk anything about the topic i rewrite articles, well i insert 1 keyword per article in the blog but i have a doubt about get high rank in google.

My plan:

-Include 1 keyword per article(more?)

-Basic SEO (title, headers,etc)(recommendations?)

-Get backlinks
|
--->negotiating /buying backlinks
|
-->Social links (twitter, rss, facebook, wikis, hubs, blogs, forums,article bases, social bookmarks)(with xgenseo)

Publicity:
Banner at the top of every single article with cloaked affiliate link.
AdSense in the right, with more widgets
A couple of buttons (at the top and at the bottom) for give the reader options to share



What do you think? my post can get index in google first page? i use various softwares(micro niche finder, xgenseo, senuke, wp plug ins for seo, web ceo) any advice about the matter?

Thx in advance
