Well how much did you get? I know for sure that if you flash the version with dalvik cache on /cache, you'll get around 154MB with the apps provided in the rom.
Either you have some app that's keeping the phone awake and not letting it sleep, or you are using the phone too much(this fix is for sleep issue only), or maybe you should just recalibrate your battery.
For the camera problem, try disabling shutter sound in camera options. It worked for me.
Well I don't believe that I can, because that was already attempted by robocik, and he did make a lot of languages available through htc wizard, but, just as more locale, it doesn't translate that much(guess because HTC pulled down all languages except english for this one as this is based on Sprint 2.1 leak).
For the camera problem, try the same thing I said above...disable shutter sound in camera options.
Friendstream widget isn't working because there isn't friendstream app to support it, but as I recall, there was no friendstream app included in sprint leak(if I am mistaken, please correct me so I can add it). I will remove it in one of the next updates...that one and news widget > you've got news and weather app with widgets
Whenever you plug in you phone to USB it will stay awake, so don't worry, that's normal. When you take it off USB, it will behave as it should
For all >>> I have uploaded no wipe update with HeroLED app which will make LED notifications and keyboard backlight work again and also I have provided a new libgps.so which should, I hope, fix the issue that you have been having with gps. (it is a bit late here, so I couldn't have tested it if it really fixes gps)
