Post title and links?

no settings for that; you will need to edit some template files.

imho, it makes sense to have the links on the front page;

if you don’t want the post titles linked in single posts, you could edit single.php, and remove the link code:

example from twenty ten:
with links (from loop.php; your theme might look different):
<h2 class="entry-title"><a href="<?php the_permalink(); ?>" title="<?php printf( esc_attr__( 'Permalink to %s', 'twentyten' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark"><?php the_title(); ?></a></h2>

without links it would look like:
<h2 class="entry-title><?php the_title(); ?></h2>

if your theme does not have a single.php template, copy index.php and save it as single.php, then make the edits in there.
