Few questions relating to Ys.

[strings]

I miss playing Ys games and I'm thinking of buying a psp again, or get a vita as Celceta is the only Ys game I've yet to play. The downside to that is that's all I'm interested on Vita is there any way to play the psp games on vita also?
Lastly, what is a good place to buy Ys soundtracks? Been having trouble finding soundtracks that accept international shipping.

Cheers!

The Vita itself isn't backwards compatible, but it can play digital PSP games. IIRC, though, the PSP selection on PSN via the Vita is incomplete, so I dunno if the Ys games are offered.
For Ys soundtracks, Esterior's FAQ has a guide for ordering directly from Falcom's site. For something more accessible, iTunes and Amazon have a surprising amount of Falcom's soundtracks for relatively reasonable prices.
