Content text limit

I am looking for a plugin that will allow me to choose the style output for each blog post.
style that include, display header (Y/N), display body (context) and number of lines/characters to display, allow grapphics to be displayed (Y/N) etc..

an example of a blog screen showing an example:
Recent Forum Posts

Light Room/ Shadowbox effects for exposure room videos embedded in wordpress Ciro Candia 20 days ago

The past did not columize the paste so well but you see a string and a poster and # of days since

DO we have, are we working on, may we create, is anyone else interested in something like this?
