Q: I have Cast Through Time in play and play Treasured Find. The card "Treasured Find" gets exiled as it resolves, but will I have the option to cast it during my next upkeep due to Rebound?
Q: I cast Treasured Find. Does it ever hit the graveyard for effects such as my opponent's Vulturous Zombie?
Q1: Rebound won't apply because it is exiled as a part of Treasured Find's own effect before it can apply. It doesn't matter that it goes to the same place.

6/15/2010: If a spell moves itself into another zone as part of its resolution (as Arc Blade, All Suns' Dawn, and Beacon of Unrest do), rebound won't get a chance to apply.
Q2: No, Treasured Find is exiled directly from the stack as it resolves.
