since version 0.23, you can define HTML tags and CSS classes for each element. So as Deryk said, you can accomplish most of what you need with CSS.
- Didnt’ really get what you need here, but check the README file, there’s lots of customizations you can do.
- You can set a thumbnail_class and then style it with CSS.
- You can set an HTML tag and CSS class for the post title with title_tag and title_class, and you could set display:none for the class you used in your CSS.
- Do you mean first ‘n’ lines from the post? There’s nothing coded for this, but you can use the excerpt and set how many characters to display with excerpt_size
