As Noach mi Frankfurt said in a comment, there are four English translations: Soncino, Neusner, Artscroll, and Koren/Steinsaltz, and Kfir Shlomo noted a fifth edited by A. Zvi Ehrman. I've worked with three of them; I don't know Neusner or Ehrman. Based on my experience, for a beginner I recommend the Koren/Steinsaltz, accompanied by a study partner or, at the very least, an introduction to talmud. None of these translations are particularly aimed for young adults, though; you will encounter unfamiliar words, concepts, and styles of reasoning. (That's why the study partner and the introductory text are important.)
The Koren edition is nearly complete now, a new volume every couple months to keep up with the daf yomi. Here's an Amazon link to the first volume, B'rachot. This edition has extensive notes; they're not targeted for young adults and you may find some of the concepts a little difficult, but with talmud you just have to dive in. The Koren/Steinsaltz edition, unlike the others, does not use a facing-page layout where you can easily see the original text alongside the translation; for a more-advanced student this is an impediment but, based on my experience when I was just starting, I don't think you'll mind this.
Talmud is hard to do on your own, especially as a beginner, so if you can get yourself a chevruta (a study partner), please do. When I wanted to start learning some years ago I asked my rabbi if he could match me up with another member of the congregation; if you belong to a congregation, try that.
If you are going to study alone, and perhaps even if you will study with a partner, I also recommend first reading a book about the talmud and how it works to help orient you. One such book is The Essential Talmud by Rabbi Steinsaltz.
I also come from a Reform background and am not fluent in Aramaic and Hebrew (working on it, ever so slowly). I've studied from Artscroll with a rabbi (who could alert me to the liberties they sometimes take as we encountered them), I use the Soncino translation to try to follow along, sporadically, with the daf yomi (because I have a digital copy of the whole thing), and I'm slowly adding the Koren/Steinsaltz volumes to my personal library and exploring them as they come in.
