Answer 1

You have to remove the default margin of paragraphs, set by browsers by default;
p { margin: 0; }
EDIT I restructured your html (set correct indents), you'll see you actually open up <p> tags, but don't close them. Either remove them, or close them properly on appropriate places.
EDIT 2 As you're using wordpress, most probably wpautop is messing with you. Try to put this in wp-content/themese/YOUR-THEME/functions.php
function my_theme_init() {
remove_filter('the_content', 'wpautop');
}
add_action('init', 'my_theme_init');
NB: if you're not using a child theme you're doing it wrong. So when I say YOUR-THEME above, of course I mean YOUR-CHILD-THEME
