Thank you, great suggestions. Point by point:
1) Why is this better?
2) Started out using CSS3, but found this easier to accommodate older browsers. Maybe I should do both?
3) Tried to make it look like the Google Map bubble, that's why it's different.
4) OK, will test.
5) Second paragraph is somewhat of a subtext to come to the conclusion in the third paragraph, but you're right in that it screws up rhythm.
6) Yep, that's a non-designer trying design for ya.
7) It has the same left-margin as the other headers and most paragraphs, but the leading dots give a somewhat false illusion, I think.
8) Thanks, good suggestion, will do.
Responding to 2) in my experience as a web developer divs are generally no longer used to round corners because the market share of the browsers which don't support css3 rounded corners is increasingly negligible.
Personally I prefer CSS3 rounded corners because they do a better job of decoupling design, functionality and content (which in a perfect world would each fit completely into css, js and html respectively).
EDIT: Looks like rounded corners only got added to ie9 so Google's ie7 stuff is irrelevant, my guess: a degraded experience on ie8 is generally taken as acceptable.
For a fluid layout with rounded corners I would have probably gone with CSS3 (versus corner divs), but since the block is fixed-size I could just suffice with one bubble.png as the background to upgrade the ie8 experience. And left it at that, being pragmatic and all.
