WP Show Posts CSS codes

Hi,

I have included the code to show WPSP on my home page and would like to know whether it's possible to add/modify the following by using CSS or not:

1 - Read more button color and borders
2 - Post title color
3 - Show the last updated date instead of published date
4 - Borders to each post
5 - Keep the same heights for all of the posts
6 - Instead of pagination, show something like "see more posts" and load another 5 more

Thanks a lot!

Regards
