You can add the code below (modify to suite, of course) to:
1 – Your theme’s functions.php file. It may get overwritten the next time you update your theme.
2 – The EE custom files add-on in the custom_functions.php file.
3 – Use this blank plugin to hold the custom function.

Do I need to add the code to both functions and custom_functions?

No, only add it to one of those 3 options.

Is there a specific location in teh functions file I should include the code?

Probably the easiest for you would be to use the third option, download the zip in the link, upload it as a plugin to your site through the wp-admin plugins interface and activate it. Then access the site’s files over ftp and go to the wp-content/plugins/CustomFunctionsPlugin/ folder and open the file CustomFunctionsPlugin.php and add the above code to the bottom of the file, below the comment block (that’s the plugin header).

What is my end result after adding the code – will it create a new payment gateway, or automatically add Square to the payment screen for registration?

It will just add the link to square to the payment screen, next to the paypal button.

Should I be replacing the square.com with my full item url for the customer to check out?

Yes, replace the href value (what’s in quotes next to href=) with the full item url that you get from square. Also replace the image src (what’s in quotes next to src=) with a link to an appropriate button image. (square should provide a link or an image file that you can upload to the media section of WP)
