While you should do what makes you comfortable, I know a gazillion people who put their children in trailers at nine months. Personally, I don't think I would go 90 minutes, but I had no problems with 10-15 minute trips with my kid.
I chose not to use a helmet, since we went on quite streets and paths, and the helmet just adds more weight to her head. Just be careful with bumps. As for napping, judicious placement of pillows and rolled up blankets should do the trick.
