A small correction.

We should use priority of “11 or higher” to make sure the child theme functions will be loaded last.

So the correct code will be,

<?php

/**
 * Add action to remove parent function "expound_setup" using function "remove_expound_setup"
 * Parent theme uses the default priority of 10
 * We are using priority 99 to make sure the child theme functions will be loaded last
 */
add_action( 'after_setup_theme', 'remove_expound_setup', 99 );

// Remove parent function "expound_setup" and override it with "override_expound_setup" function
function remove_expound_setup () {
	remove_action( 'after_setup_theme', 'expound_setup' );
	add_action( 'after_setup_theme', 'override_expound_setup' );
}

if ( ! function_exists( 'override_expound_setup' ) ) :
/**
 * Sets up theme defaults and registers support for various WordPress features.
 *
 * Note that this function is hooked into the after_setup_theme hook, which runs
 * before the init hook. The init hook is too late for some features, such as indicating
 * support post thumbnails.

What do you want to include in the footer?

As mentioned in the 2nd post, you can add that code to functions.php in your child theme. Then copy paste the footer.php file to your child thema and add an action to include your custom copyright.

If you want to change the way the footer is displayed, then you need to edit the CSS related to footer.

You can do that by adding a plugin like, http://wordpress.org/plugins/fitvids-for-wordpress/, or some other plugin like that.

Did you make any custom edits?

I think its not possible to cannot change the excerpt length for just the secondary featured area as the codes for excerpt length are in the wordpress core files.

You can change the excerpt length for all posts in functions.php.

/**
 * Change excerpt length to 10. Default is 55.
 */
function custom_excerpt_length( $length ) {
	return 10;
}
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );

http://codex.wordpress.org/Function_Reference/the_excerpt#Control_Excerpt_Length_using_Filters

/**
 * Change excerpt length to 0 and remove the ... that is displayed.
 */
function custom_excerpt_length( $length ) {
	return 0;
}
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );

function custom_excerpt_more( $more ) {
	return '';
}
add_filter( 'excerpt_more', 'custom_excerpt_more', 999 );

Not sure what he meant by “duplicate tables”. But those 4 posts can be made to be displayed as 2 posts per line.

In expound.css

Find:

.featured-content-secondary article {
  margin-left: 10px;
  margin-right: 10px;
  width: 220px;
  float: left;
}

Replace with:

.featured-content-secondary article {
  margin-left: 40px;
  margin-right: 40px;
  width: 440px;
  float: left;
}

Its much better if you make a child them to do this so that custom edits are preserved after theme update.

/*
Theme Name: Expound Child
Template: expound
*/

@import url("../expound/style.css");

/* =Theme customization starts here
-------------------------------------------------------------- */

.featured-content-secondary article {
  margin-left: 40px;
  margin-right: 40px;
  width: 440px;
  float: left;
}
