Hi Ronny,
1) no (15 mins is enough), there is no queuing system at the platform; when the train arrives, you have to fight to get your bike on first if it’s busy. There is never any guarantee for a bike. But I’ve never had a problem, don’t be polite, be dominant and show people this bike is getting on the train whether they like it or not.
2) you pay with the train conductor onboard when you show them your seat ticket. You pay by card, and the price is based on distance. The max should not be more than 255kr (24 euros)
