What would I need to do to learn how to edit and create my own beats?

YouTube is a very important tool to use. learn how to make beats as a beginner just be sure to type in the type of instrument you're working with software or drum machine
A sample .. make sure you're clear on what you're talking about are you trying to make beats are you trying to make music

The easiest way to get started creating beats (in my opinion) is to work with Garageband or Fruity Loops type of programs/apps. They give you a loop browser (loops are pre-made rhythms and short bits of music) and the program allows you to just drag pre-recorded loops into a time line and created your own mix of those loops. This will give you the most interesting and quick way to create beats. The bad news is that your beats will sound like other people's beats because you are using the same library of loops. But.. at least you can get started.
Most public libraries allow you to get on their computers and use Lynda.com (Lynda.com is a resource for you to learn about subjects like music/audio, video, and many other subjects). I know that if you have a library card in San Francisco, you have free access to Lynda.com in the library or at home.

I hope this helps! Ask your friends that are making beats how they do it and there are lots of other resources on line. Personally, I use Apple's Logic, Pro Tools, Ableton, and other programs to do this. The reason that I suggest Garageband or something similar is that it is very accessible and you can get started quickly.

Good luck

"Beats" is an ambiguous term. Look it up. Many different definitions.
In the US Air Force, we called it OJT - on the job training. Learn by doing and by failing. These days, it can be done at a fraction of the cost (equipment) of what it was even 20 years ago. Cheap cameras, editing programs, etc. Don't need the highest end cameras, etc. Your story is the most important thing.

Get a copy of Ableton Live or Logic and jump on YouTube and watch some tutorials.
