For {Shelldock Isle} do you only get to play the hidden card once? Just wondering:)
702.74a (http://imtgapp.com/forum/index.php?action=imtg;area=rule;number=702.74a): Hideaway represents a static ability and a triggered ability. "Hideaway" means "This permanent enters the battlefield tapped" and "When this permanent enters the battlefield, look at the top four cards of your library. Exile one of them face down and put the rest on the bottom of your library in any order. The exiled card gains 'Any player who has controlled the permanent that exiled this card may look at this card in the exile zone.'"
This is all the glossary had on hideaway..
Once you play the card, it goes to the zone it would as if you played it from your hand. For example, a creature card would go to the battlefield and a sorcery card would go to the graveyard. So since that card is no longer exiled face down from hideaway, you won't have the opportunity to cast the card a second time.
If I understand what you are asking, it stays in play. When an effect says "cast" treat it as if it was entering from your hand (except if the card has text that says it can only be cast from your hand)

Basically correct, both you and Drain, but you're simply casting it from exile. It wont trigger anything that triggers when you cast something from your hand. You put it on the stack from exile, and it resolves like any other spell you would cast.
Thank you:)
