I found that a local game development company is hiring a QA Tester, and I would like some advice on what to put in my resume.

-The position really only requires English written and speaking abilities. Past experience is not required, but is a plus.
-I have no previous experience working in game development aside from my few personal projects.

-I currently work as a supervisor at a big box retailer. Is that experience worth putting on my resume? (I must communicate effectively to my team, I was also involved in training new associates, solve customers problems, fast-paced high-pressure job where I've had to juggle multiple tasks at once)
-I'm a student studying computer science, with the goal of becoming a programmer in the game industry.
-Should I include other activities on my resume, such as my Eagle Scout achievement and participation in Toast Masters public speaking class in high school?

Thanks for the help, I really appreciate it.
