Question one: Suggestion on how to flush out calcium crap on bottom of water heater tank? I stuck my finger in there and feels like 1/4 inch of sand on bottom of tank.
Question two: Once I'm done, how do I refill WH tank? Turn on water pump and open hot water faucet? How do I know once the WH is full?
I don't want to run heat to WH until I refill it so I don't fry any heating element.

The calcium should not be clogging your toilet unless you've been draining your plumbing system before you drain your water heater. You should close the inlet/outlet valves on your water heater before you drain your plumbing system. If you don't, you pull the calcium backwards from your water heater into the cold water supply line. THEN it can get to the toilet.
If you have been draining properly, then I'm guessing you have something other than calcium in your toilet valve.
