I'd personally go with Castlevania first, off of that list. I would have reccomended buying Ace Attorney 2 (buy the game, lets Capcom know we want it) but we're already getting Ace Attorney 3. So it's safe to rent that one. Definitely play it.

Save Tales of the Abyss for your birthday. You've waited 10 years to play FF7, you can wait longer to borrow it from your rarely-seen friend. I heard Tactics was pretty okay too, but despite having it in my possession I haven't played it much (Friend left it over my house months ago before he went away to school, and I have no PS1 memory card).
