PDFs are indexed, it won't hurt you to put the texts up as HTML on the website, though.
What I suggest:
- Put up the FAQ as a HTML page, with a link to the PDF.
- Write a short intro/summary for the other material to go with the link to the PDF.
(50-100 words)
Now, the real problem I see is with your starting page, but it is human-related, not SEO related.
The text is basically unreadable.
Try breaking it up into paragraphs, think about some headers, maybe a bulleted list.
Your users will like it far more than that blob of unformatted text you have there.
