Here’s my best advice to you at this particular time in your journey:
I admire your zeal for the craft, but stop reading/researching on the internet. Yes, you will find some useful information, but there is just as much misinformation out there. Part of the experience is finding out what you need to know from your brothers and mentors. Don’t hurry the process.
As you move through your degrees you will learn information and meanings about different symbols. If you hear or see a symbol, story, or idea from your current degree that has not been explained then ask your assigned mentor about it. They should be able to tell you something about it, and if they don’t know then they need to find out or find someone who does.
But don’t try to jump ahead and outside of the degree you should be concentrating on, in your case the Entered Apprentice degree and it’s symbology (paraphernalia you wore during the degree, working tools, jewels worn by the officers, Great Lights, Lesser Lights, etc.)
As for pins, rings and such, forget about them for the time being. In most jurisdiction you can’t wear them anyway until you finish the 3rd degree, and there is a reason for that also.
Enjoy the experience.
