Creating Traffic with content questions

[Giraz john]

This is a quote from willcode4beer on another post..."Create content that is useful and interesting. When you have interesting stuff on your site, folks will naturally link to it. When it has genuinely useful information, people will just link to it."

If I successfully create content that is useful and interesting, what next? How do I best go about getting people to see my content for the first time?
How often do I need to update fresh content to be effective?
Are video's and picture's a must?
Anything else I may be missing?

Also concerning building links for SEO...
I have read on this, but still find myself having trouble getting this aspect going. I've been told that a link page is probable not the best way to go.
If I do not have a link page then where do I put all of the links that I link with?
Should I try and get one-way links from top rated sites and if so how does one do this?
Anything else that I may be missing?

I am going now to read up here and learn what I can. Infact, I am going to devote at least one hour a day on study here and other places reliable people here suggest. I appreciate any help...
