Why don't you use something the function html_entity_decode. 
http://php.net/html_entity_decode

$node->field_book_title['und']['0']['value'] = 
html_entity_decode($node->field_book_title['und']['0']['value'],ENT_QUOTES);

For your second question, look at the function nl2br(), http://php.net/nl2br
