No pages Showing in Google Index

I just setup my blog about a month ago. When I use the site:mydomain.com command all I get is my homepage. I do have several pages created: disclosure, terms of use, and coupons. I use categories to organize my posts. Google webmaster suggestions show duplicate meta tag descriptions for the 5 pages of posts that are shown in navigation bar at the bottom of my homepage.

1) Do I need to worry about the duplicate meta tag errors?

2) I did not enter title tag or meta descriptions for disclosure, TOU, and coupons so I understand now why the pages are not showing up.

3) Do I need to create pages to help with my sites SEO?

Any advice is truly appreciated.
