If the user has an active account with Google and their setting on the phone is set to backup automatically, really all you need to do is stick your pictures and stuff on your SD and transfer it to the new phone. When the new phone is booted, you login to your Google account and the system will ask if you want all apps restored from the old device or not. I do it all the time in my work testing. If there are any non-Google Play apps, don't forget to not loose the original install APKs. You will need to install those again manually and the new device must be set to allow non-Google play app installations.
Want to use your PC? Just connect to the PC, set the transfer mode in the device to file transfer and you should see it in Explorer. Drag/copy/drop
A PC connected to the Internet should have a driver installed automatically, if needed.
