Using <HX> tags to present page hierarchy

Does it work?

[Livenomadic]

I'm writing my site for better xhtml complience and SEO.

I have quite a few multi-page articles.

The articles have:

Article Title: The title of the entire article
Page Title: The title of that specific page of the article.
Paragraph Titles: The titles of paragraphs inside the article

For SEO I wanted to wrap each title in a different sized header tag:

Article Title: <h1>
Page Title: <h2>
Paragraph Titles: <h3>

My theory is that it should be clear to google that the article title is the MOST IMPORTANT, the page title is SECOND MOST IMPORTANT, and the paragraph title is the THIRD MOST IMPORTANT.

1) Does anyone see anything wrong with this? I am worried google might freak because I have so many header tags in my document.

2) Silly just-in-case question: If I have a h1 tag but I use CSS to make it appear smaller in size h1 is ridiculously large, will google still consider it a h1?

Thanks everyone!
