(Text ) How to indent specific parts of blog

Dear WordPress Gurus,

I have here a modified F8-lite theme. My problem is I want to indent the Post Titles and the Headings when I go to individual posts.

In the Main page, the indentations are OK when the archive of all posts are viewed but when i click the individual entry the heading becomes flushed to the left.

For comparison here is the main page:

while this the page where i am having problems with text indentation:

I would also want to indent the first and leftmost widget at the bottom of the page. It is also possible to embed images in the widgets?

Is it also possible to add a random image thumbnail in the widget area?

Sorry for the multiple questions. Am still new in WordPress and any help will be appreciated.

Many thanks!
