Ah okay, I know you can have iphoto open by default when you plug in the card or camera. I think best way is to store it all yourself in the location that suits you. Make the folders, drag them there from your memory card and then open it up in photoshop.
I think Bridge will import them, Bridge comes with most Adobe products I think and will allow you to do the organising thing that iphoto does. I haven't used either in ages, but I'm pretty sure in both programs you can specify where it puts the files. I just find it's easier if I put them there myself.
I then import them to my aperture library (leaving them in their original location, not making duplicates or moving them) where I can edit/tag/rate. I barely use photoshop for editing now, there was only one pic out of 600 or so that I used photoshop for just recently.
