How to promote? Need some help

Hi, I will be launching an authority site soon, with heatmap theme, unique 700+ word articles, and I plan on monetizing with adsense and maybe I'll put some amazon products in the mix, but the aim is adsense.

I need some help with promotion, and backlink creation. Many of the info I can find using search function (I am aware this question has been asked a zillion times) is very much tailored for US and english sites, but my website will be for Spain.

Right now I am thinking of doing this:

- facebook fan page, and keep updating it daily with fun images or videos for my niche
- twitter, and at least one new tweet a day
- manually submiting to a couple directories a day for the first weeks
- joining a couple of forums related to my niche and post useful info there, with my signature.
- yahoo answers in spanish. Posting answers that are useful, with my link

Now my questions:

- would it be a good idea to create a wordpress.org and blogger blogs, and post stuff, and put links in those posts to my site? Or that would be frowned by google?
- do you guys know of article directories that accept articles in spanish?
- which other social profile or other types of good websites that would allow spanish would you recommend? As you can see I can write in english so maybe I could create or comment in english but put my link for spanish website too.

Anyway, any tip and help will be greately (enormously) appreciated. Just refrain from offering me services (I cant invest money, only time in this project) and keep in mind I NEED to do only things that google will like, cant allow myself to do stupid stuff or rush, and then get deindexed or lose my adsense, it would kill me!

Thankyou and bless ya
