Answer 1

Firstly, the best method I have found (superior to Adobe Import/Convert/Export) is to install the software from the A300 CD - I know, blasphemy. Anyhow, you can delete all except for the RAW Image Converter, which lets you do raw editing, its decent, and then export into whatever file type and size that is convenient for you, though its not the same as native Raw support, I know.
Quirks: Not many, its a great camera, I've had mine for about a month and a half now. The AF Assist light drains battery like an electric car, and I can't say that I totally appreciate the inability to invert the focus ring direction. Ergonomics whilst wearing glasses is mediocre at best and your screen will get dirty - you'll have to deal with it. Otherwise, its absolutely an amazing camera, DO NOT RETURN YOURS!!! As you can see, there are a few quirks, but if I were to write down its positives above cameras prices three times as much, the list would take up pages. keep it, its too good to care for the little things like that.
