Excellent.
If I were you, I'd hold onto the Ratchet Collection because 2 & 3 especially are excellent games which still hold up today.
I'd recommend keeping PSABR as well, but it's not for everyone. One thing you could potentially do, if you were trading it in at a store is download the "cross buy" version of the game to your account before you sell it/trade it in. That way, if you ever pick up a Vita in the future you'd have the game. Though I suppose it depends how much money (if any) you'd lose from selling a new copy vs. a used one.
Nice selection of JRPG's anyway. You might consider picking up Atelier Ayesha just to get yourself customised with both the series and the universe before you get the new Atelier.
I'd also recommend the Metal Gear Solid Collection. I won't claim to know your gaming tastes but judging by the selection of games you've listed, I suppose you quite like storytelling? The Legacy Collection is a great way to get into the series and I think you'd probably quite like it.
Enjoy.
