It's hard to reccommend a specific template without knowing lots more about your training history (something I need to do with my clients), so I would reccommend that you start with the basic template from the book -- especially if it looks similar to what you were doing before.
The weights should adjust to your current strength level because you'll be using the RPE to govern how much weight you put on the bar.
RTS was designed to be worked through slowly. If you start with what you know and modify it as you go through the book, then by the time you finish, you've learned a lot about how to train yourself.
Let me know if any of that helps. I'd be glad to answer any other questions you have as well.
