If I'm loading my jQuery scripts below all of my page HTML, do I still need to wait for $(document).ready to be able to use jQuery to find elements in the page?

No, it is not necessary.
It is in no way required. All it does is make sure that the DOM is loaded before trying to query for and use the elements inside the DOM (usually after dom is ready and before body. onload fires). You can use jquery perfectly fine without it.
$( document ). ready()A page can't be manipulated safely until the document is "ready." jQuery detects this state of readiness for you. Code included inside $( document ). ready() will only run once the page Document Object Model (DOM) is ready for JavaScript code to execute.
jQuery $(document). ready() is a basic part of using jQuery. The jQuery document ready function executes when the DOM (Document Object Model) is completely loaded in the browser. jQuery document ready is used to initialize jQuery/JavaScript code after the DOM is ready, and is used most times when working with jQuery.
No because the document would have already been loaded. The Dom loads top to bottom. I personally like to put all my js at the bottom of the page instead of in the head.
however it is only 1 line of code and i would suggest using it just to be safe. also you can make it even shorter. $(function() {} is the same as $(document).ready(function(){})
