As per my experience i found that Blogging, Article, Fourm and as on is effective but for blogging and article submission, use should use fresh content use proper keyword and all i think that is effective.

All of the above but articles especially are a good method.

In link building I think its better to use different technique, Just like what you've mentioned.

Article submission, classified submission & press release submission are effective method of seo.
