https://steemd.com/ is a great place for a lot of what you're looking for. Along the right hand side of the main page, you will find some of the total values regarding the money supply.
current_supply

current_sbd_supply
510,049.408 SBD
total_vesting_fund_steem
100,954,503.525 STEEM
You can determine how much STEEM is powered up with a simple formula:
1 - ( total_vesting_fund_steem / current_supply )
That will show you that currently 97.923% of STEEM is in the powered up state.
The other figures are harder to pin down... I'd recommend you give Black Box wines a try, they're actually pretty damn good and a wonderful value.
