Your enthusiasm and passion for Judaism is moving. Judaism, as you are discovering, is a meaningful and wise tradition; I think I can speak for my colleagues across the denominations in saying that we welcome your interest.
It is a longstanding Jewish tradition that in the synagogue there is a light above the ark that is kept on continuously. This Ner Tamid (Eternal Light) reminds us of the menorah (candelabra) described in Exodus 27 but it also signifies that the synagogue is a place where, as they used to say in the Motel 6 commercials, “we’ll leave the light on for ya.’” In other words, the synagogue is a place open to all whenever they need it.
Most synagogue services are open to anyone who wishes to attend and we strive to be like our ancestor Abraham who welcomed every stranger who approached him. I strongly suggest that you visit several synagogues of varying denominations in your area. You don’t need permission, but it doesn’t hurt to call ahead to find out more about the synagogue and its services. For security reasons, some synagogues are cautious about visitors. If you let them know you are coming, they’ll be more likely to reach out to you. Either way, you should definitely introduce yourself to the rabbi and anyone else who looks friendly.
While it’s true that Reform synagogues tend to use more English in their services, virtually all synagogues will have prayer books with translation and some may even provide a transliterated prayer book (with the Hebrew written phonetically in English letters).
The other recommendation I have is that you should find out more about classes that are available in your area. Many communities offer an “Introduction to Judaism” course for those exploring Judaism for the first time. There are also a number of wonderful books out there to get your started. A local rabbi or Intro to Judaism class can point you in the right direction.
Blessings on your journey.
