Is there a photoshop feature in Photos? Other than the crop, move, etc. that appears by clicking the picture? I want to touch up some photos

How are you transferring your pictures to Shutterfly? One way is to use the "Media Browser" when asked to upload a pictures-- the dialog looks like this:

You can use the search feature to locate a particular photo, or scroll through the library. You've indicated you're using Yosemite which is a bit old, so your "Media Browser" may look different. You can also use the this Media Browser to go through albums to find the pictures you want. Using this browser method will load the edited image.

You can also drag the image thumbnail from the Photos window to the website, but it's not always clear what that does-- for me it exports the edited picture, but that may not be the way your version works-- dragging is iffy.

You can use File>Export>Export nn Photos to send edited pictures to a folder on the desktop, and then point the website to that folder.

Making Photo books seemed easier with the old iPhoto-- now you send the pictures to the company of your choice. If you control-click on a picture and choose "Create" it will send you to the App Store with suggestions of places that will take pictures from Photos and make books or calendars or whatever. I have used a company called Mpix, but I didn't use the Photos interface-- I sent the pictures to a folder and sent the folder to the company. You just have to see which company works best for you.

There is a whole array of editing tools. To edit, you click on a thumbnail and hit "return."

It looks like you're running Yosemite, which is about six years old (about 75 in computer years!) Are you running the program Photos, or the old iPhoto? The number of editing tools has really blossomed in the last few years.

This page of the user guide and the following pages explain how to touch up photos in Photos: Photo editing basics in Photos on Mac – Apple Support (UK)

Photos has quite a lot of editing tools:

iPhoto has a number of these but it's really increased in capability with Photos.
