1. They're two different devices. iPod Touch is essentially an iPhone sans cellular phone. Thinner, too.
2. Overall, it's more powerful than either. Once you factor in the large OS compared to the DS/PSP, it's hard to say. It appears to be somewhere in between the two devices in actual performance.
3. A bit smaller than the PSP without measuring them exactly (I own both).
