Replying to post text doesn't go all the way across module

Follow http://ithemes.com/codex/page/Ionic#To_show_posts_in_a_typical_linear_pattern_instead_of_columns

To display full post content instead of excerpts, edit child theme's index.php and change

<?php the_excerpt(); ?>

to

<?php the_content(); ?>

In my site, thetvmentors.com, I have to have a content module up in order for my home page to function correctly but when I write something into a post it wraps the text to a very narrow margin instead of letting it go all the way across the module.

In addition it doesn't display the whole post and cuts it off with a "more" link.

I'd like to either ditch the need for the post on the home page or just enable the text to go all the way across the module.
