Is there any problem with GPS?

Most people have reported their GPS to be functioning just fine, though there have been quite a bit of variation on lock times.

There's no LED Indicator?

Correct, like all Samsung devices(minus the Epic 4G on Sprint) thus far, there is no LED indicator light. There are apps, such as NoLED, on the marketplace which work great on the Nexus S and provide more or less the same functionality.

Why have my Wifi/3G/Signal bars switched from green to white?

A green set of bars typically means that you are connected to and syncing with the Google Account servers. White means that this is not happening for whatever reason, usually something like a bad signal or low coverage area.

Also the WiFi connection is set by default to turn itself off(aka sleep mode) when the screen is off, this can be adjusted under Settings > Wireless & Networks > Wi-Fi Settings > Menu Key > Advanced > Wi-Fi Sleep Policy. Don't panic, though, it's nothing too major. (Suggested by mmas0n, thanks!)
