As for the public comment, any management plan changes are always announced on the organization's website, but they can be kind of hidden if you don't know where to look. The NPS has a centralized site for it:
https://parkplanning.nps.gov/publicHome.cfm. If I remember correctly, the BLM does it by region and the Forest Service does it on a per forest basis and the announcement is typically located in their news section. I agree it isn't always easy to find or to figure out what is going on, but calling or emailing the park/forest offices is always an option. You might have a hard time getting a hold of someone during the field season (everyone wants to get outside as much as you do), but many people working in these places are passionate and very nice. They are actually there to help and don't mind fielding questions and chatting about it.
