any way to squeeze something extra in to the default setup?

sorry for the vague title, couldn’t think of a better way to state it. here’s the quick story:

all posts in my blog are of a similar format
1) post title
2) large picture
3) a single paragraph of text
4) misc (could be another image, a swf, more text paragraphs, a few related links, etc.)

i’m trying to squeeze a “digg” button around just the first paragraph of text, #3 above. i’ve tried a few ways, but just can’t figure out a working way.

my first attempt used CSS to place the digg button using “position: absolute” to plop it in beneath the title and picture, 1 and 2 above. i got the digg button in the proper spot, but because it wasn’t actually “there”, the text wouldn’t wrap around.

my second attempt tried to use CSS to style just the <P> tag for item #3 above. i figured i could make that column narrower, then place a column for the digg button at its side. however, i couldn’t figure if it was possible to style just a single P tag (and because i don’t want to retroactively add a named div to my thousands of older posts, i had to play with just the default code)

for my third attempt… i came here! 🙂 any better ideas?

if it helps, here’s a page to give you a general idea of the overall format: http://toonbarn.com/2009/10/disney-and-marvel-are-bff/
