The general idea is that clearly separated data layers don't pose any problem. 
So, balloons with news items? As long as you can tell the balloons apart from 
the map and the map apart from the balloons, go ahead!

Yep.

"Data CC-BY-SA, OpenStreetMap.org contributors" would be a little bit better 
for both cases. Change the "(C)" by "CC-BY-SA" in any case. Please do link to 
openstreetmap.org in the map in the webpage.

If the screen real estate is really precious, it could be shaved off 
to "CC-BY-SA OpenStreetMap" or even just "OpenStreetMap" 
or "OpenStreetMap.org". Remember that the CC-BY-SA license asks for 
attribution "reasonable to the medium".
