Anyone can tell me where i should start from and Which host is suitable for me?

1) I want to build a website (or blog? I'm not sure, pls tell me) to introduce various foods and restaurants.

* I'm going to update the site daily (or twice a week), since some restaurants will have promotions regularly.

* I want to allow my website visitors to write some reviews on a specified restaurant/an article.

* Besides of my articles, i want to have a one-page discussion forum, visitors can freely chat there and the contents/topic in the discussion forum will be on a "first in first out" basis (I do not want to store it permanently).

* Also every registered user will have 1 point each time they post a message on the forum.

Do you think I can build such a website (or blog?) without html knowledge (i can learn it if necessary). Thanks.
