1. I know a few people who are in PM roles, some who've been a PM at multiple companies including startups and corporations alike that are non-technical. Being technical certainly helps but there are roles there that exist for non-technical folks as well. (These are in Silicon Valley/SF)
2. Base on people I know that have went through DevBootcamp, its certainly a good introduction if you have an interest in programming. But from what I've seen, people who graduate (that I know) while can code, still need quite a bit of help. I guess if the goal is to be a PM where you aren't writing code if that is a requirement, it would be a good fit.
