The PSP PlayGear will work well with older (PSP-1000) models, but won't work with the PSPGo
They only work on American Psp's because they are off the same region.
No, the PSP GO has no UMD slot.
No. If you have psp 3000 it will but any other psp it will work.

No
As long as you have WiFi, then yes. You cannot get on it without WiFi.
There's no such thing as a PSP game that's model specific, they'll work on any PSP. However the PSP GO has no UMD drive, so of course, those won't work. Any PSP game available on the PSN though will work on both PSP 2000 and PSP GO.
Yes, all PSP games are specifically developed for the PSP console so they will all work. The same cannot be said of PS Vita games, Vita games won't work on the PSP.
