Trans-scanning should always increase card's stats some. You can see the result before the process takes place.

Note that since it resets a card's level down to 1, if the cards you were using to trans-scan had been leveled, the new trans-scanned card could actually be weaker, but will eventually become stronger as you level it again.

And yeah, I don't understand why all those social CCGs always force you to evolve/trans-scan/fuse your first good rare, knowing it will make it crap since it wasn't leveled prior to that.

"Reset" on the upgrade screen will just remove the card you were about to upgrade and the cards used for the upgrade process (they are not lost, just put back in your base). It just resets the screen to its default status, should you want to pick a different card to upgrade, or choose different cards to upgrade with without having to remove every single one of them manually : )
