GTA San Andreas is not a PSP game and can not be downloaded for the PSP. The below procedure works for PSP games First you connect to the PlayStation Network from the PSP's menu bar. After you've made an account, you need to put some funds into it, using a credit card - I think you can buy credit at game stores too in the form of a redeemable points card. Once this is done, you can buy the game from the PSN, and download it to PSP.
