Got a 75 gallon tank and stand from craigslist! 

Outside of needing a new hood its in good condition, and the guy also gave me his canister filter. This is significantly larger than my current tank so I realize filtering and heating are going to need to be handled differently and rather than blunder about and end hurting or killing my fishies I would rather you fine individuals fill my head with the right way to do this.
75 gallon tank
Fish:
2x Senegal Bichir
1x Ropefish
1x Leopard Bush Fish
5x Giant danio
1x BGK
What do I need for my heating, my filtration, my substrate etc...
