Okay, so does it matter what proof setup setting I use, as long as RGB for web and CMYK for print? And what does 'proof colours' show me when it's on, and when it's off?

I shoot in Adobe98 and export as sRGB when using the images for web - correct? If I was sending an image to print, I would keep the Adobe98 colourspace and work in CMYK - correct?

I don't want it to be complicated! I do think it's important to understand how it works though.

i think you need to do some googling as it's not a question of answering a yes or no.
and there are lots of if's and but's and i don't think one reply on a forum is going to be the answer.

work in RGB then convert to cmyk if you have a print profile as generic cmyk is not how it's going to print .

sRGB for web? yes. a smaller colour gamut that should work well on all devices/platforms/browsers.
