How many megapixels?

I think 10MP would be lots for 8x10 and 16x20. However I'm pretty sure when it comes to these compact cameras pixels means very little as the sensor size never increases and sometimes even gets smaller. Typically the density increases and from my understanding is that rarely means much more than a number used for marketing. It's why you can look at full frame cameras which have large sensors yet usually only around 12MP while the latest and greatest tiny compact has 25MP on a sensor a fraction of the size.

I also have a G9 and love it so if you're in the market I would consider something similar, maybe G10 or even the 11 or whatever number they are at now. Just be sure to check specs and compare, sometimes the new cameras are worse than the older ones.

Cannon also makes an underwater case for the G cameras, I'd highly recommend it

Ya, thanks Steve! I didn't mind the G9 (I had a G7 before it)...I got some pixelation when trying to capture lower light photos. I'm not sure what specs would affect that.

I was looking at the Canon underwater cases, but was also considering the much cheaper DicaPac cases since I have to buy a whole new camera right now (trip to Kauai coming up in April). I'm thinking and underwater case would come in handy when taking macros of corals that are not near the glass and may prevent another swimming camera death!

Probably just high iso, typical with any compact, if you take slower slots with a tripod you could turn the iso down and probably reduce that quite a bit.

I wouldn't use one of those DicaPac cases except for maybe rain protection, definitely not submersible. Typically you can pick up a used G9 in good shape for $200 or less so check out kijiji or ebay. The Cannon case is only $200 so if you're planning on any diving or snorkeling then it's well worth it but if not then maybe the cheaper alternative is all you need.
