The used PSP you can get around $120 for it easily if you sell it as the bundle, meaning with the game. Amazon has them used for about that price.
The Kickass isn't really worth any value, with vita coming out and not having UMD you are limited to only viewing it on that system so there is really is no value in the movie. USB cables are dirt cheap so if you over price it, most concience consumers would pass. The car charger is a nice bonus can probably score $5 or $7 for it.
You can probably make $10 or $15 for the memory stick, but you really can't legally sell the games on it. Those games are tied to your PSN meaning you can redownload them, and whoever buys them has no way of recovering the games if they are deleted or misplaced. So I wouldn't even list them in your sale.
PSP isn't real super popular so I wouldn't try to sell the whole package higher then $140 + S&H.
BTW the god of war game lost alot of value once it became downloadable on PSN.
