1. Yes just as you described...you will be walking through the terminal with your bikes and gear. Don’t worry lots of people do this. Also when you are waiting in the terminal to get called for boarding, those with bikes will be separated off to the side. You will line up with your bikes and be called to the car where your bikes go and then take your seat anywhere on the train after docking. All of the cyclists will walk their bikes to a specific train car before the rest board the train.
2. I just posted an update about the washout, scroll down through the forums for Brunswick Culvert Washout. In short, it will not be repaired in time for your trip.
3. NPS will probably have a more specific date as April approaches. Might have to do with weather or if we have a warm spring. Keep checking their site. There should be adequate opportunities to purchase water in town but I totally understand the uncertainty of the pumps and bringing a filter.
