Replying to Etiquette For New Park Skiers

So I'm planning on getting into the park for the first time this year and starting to learn rails and butters and basic tricks. I don't know park etiquette at all. I know resorts put up signs giving basic info on how to act in the park, but are there any unspoken rules I should know about? How do I go about learning without getting in anyone's way or making an ass of myself? I climb a lot and climbers are really cool about sharing tips and beta with each other, is it okay to ask other skiers how to do something if I see them do something I think looks rad? Or am I supposed to just keep to myself and figure it out? I'll be skiing at PC & Snowbasin.
