Not exactly. You should be able to access it outside of the US, you just can't buy music without a US credit card. You're still free to upload your own music.
You might also have to manually install the Music .apk as it is region-blocked in the
Market Play Store (

)
Not without elaborate proxies. Before Google Play it was just a blank page with a generic, "Google Music is not currently available in your region".
No upload, no browse, no purchase, not even a logo.
At least now we have a logo, and a slightly more concrete message, "We're sorry. The Google Play music player is currently only available in the United States."
I previously installed the APK via App Brain as the app wasn't available for me in the Marketplace. Even then it was just a music player. Any upload features resulted in the same old, "not available" message.
