need help with additional pages

I am restructuring my dad’s website so that instead of his blog being a secondary page it will become the main page and everything else will be secondary. I have never built an entire site through wordpress before and find I am having some issues on the secondary pages, so far have only added one, the about page. My theme is a fluid one and I have chosen to have both sidebars show on all pages…my current issues are:

1. images in left sidebar show on main page (blog) but not on the about page..how do I fix this?
2. there is a comment form on the about page that I don’t want and can’t find an option to remove it
3. for whatever reason the font for the paragraphs in the middle column is different and don’t know what css to adjust to fix that

I appreciate anyone taking the time to help me with this and thank you in advance
