New Pixma iP8750

CANON PIXMA IP8750 (OS X)

Hi, I'm new to Canon Printers and, wanting to understand how best to control the (mainly) photo and artwork output, I would much appreciate help if possible with a few things I'm uncertain about:

1. Print Presets: why is Print Quality set as 'Normal' for both Draft and Fine Printing?
2. What is the PPI for Draft, Normal and Fine? And for the intermediate Custom slider settings? (Might this be something like 360/720/1440 - as in Epson)?
   
3. I see several ICC Profiles listed for the IP8750 in Printer Settings, but can find only the CanonIJPrinter2005.icc on my system.
4. If I want to use Matt Photo Paper, there is listed only 1 option - iP8700seriesMP2 ; assuming (2) refers to quality, which Quality would that be, and what if other Qualities are used?
5. What is meant please by other "Fine Art Papers"? Does this mean (digital print) coated papers or any uncoated art paper?

I will also be using 3rd Party papers and so making my own profiles for them. Presumably, I'll have to select one of the given Media types, which is why I'm wondering what Canon means is the difference between Other Fine Art Papers and Other Photo Papers?

Many thanks for any help on this.
