Excerpt instead of Full Post but need a tweak…

I’m using the Yoko theme and have changed from:

<?php /*the_content( __( 'Continue Reading →', 'yoko' ) ); ?>

to:

<?php the_excerpt() ?>

This did get me the excerpts but I have two issues.

1) It doesn’t have a link that says Continue to the full article or anything like that so I need to know how I can add that. It doesn’t show a link like that on the tags page, search page, or anything else so maybe it just wasn’t made to work that way but I’d like to add it.

2) I want to change the exceprt length to show more than the 40 words.
I found the function.php file with this section:

function yoko_excerpt_length( $length ) {
	return 40;
}
add_filter( 'excerpt_length', 'yoko_excerpt_length' );

which I changed to show

return 60;

But nothing changed. Not sure if I’m just missing something or what.
