Questions about PSN Classics games

[Dark Kabuto]

I DLed some PS1 games off PSN today. I plan to mainly play them on my PSP, is there any way I can make it so the screen is full size?

Also another question...if I decide to delete the game off my PS3, can I re-DL it at a later time without having to pay for it again?

During gameplay you can press the home button and go to 'other settings' and then 'screen mode' and you can choose how you want it displayed from there. And I do believe you can re-download things without having to repay.

Yeah you can, once you buy it it's yours forever.
