We used evenflow glass bottles with the stage one nipples and we also had a couple of lifefactory glass bottles with their stage 1 nipples. I liked them because both kinds screwed directly onto my Medela pump so I could pump directly into them and store or give DD milk right from them. We gave DD a bottle for the first time when she was about 5 weeks old, I think, and gave her one every day until she seemed good with it, and then every few days until I went back to work when she was three months. I was out of the house for the first bottle feeding, which it think is pretty key. After that, I would usually hide and pump while DD got a bottle.
The moms I know whose kids didn't take a bottle just didn't take a bottle regardless of what kind they tried, so my advice would be to keep it simple, don't worry about the Dr. Browns setup unless your LO has gas problems, and go from there.
I strongly encourage you to avoid plastic if possible.
