So much info needed! Keep reading, googling, reading, and reading.
1)If you have conditioned the water, technically you've already dechlorinated it. You can do this with plants in the tank.
4) Get an API test kit, not the strips but the little bottles. Unless your pH is wildly fluctuating or is at an extreme value don't worry too much about it. Fish will usually adapt given enough time to acclimate, consistency is usually more important.
1) Canister filter for sure - Eheim or Fluval
2)Inline Hydor heater. With a canister and an inline heater you suddenly have no junk in your tank.
1) pretty sure angels are not plant eaters
2)Anubias, Java fern, most crypts
1) You can treat water before you put it in the tank, or you can add the conditioner to the tank and then add the water. On a 40gallon tank it might be easier to use a hose instead of a bucket so add the chemical then add the water.
3)If you are using municipally treated water and the pH is a reasonable level I wouldn't worry about it. A consistent pH is likely more important than trying to maintain a specific value. Messing with parameters always seems to lead to heartache, you aren't planning on keeping anything with a specific pH neediness like shrimp so I wouldn't worry too much about that. My water sits steady at about 7.5
Hopefully now someone else will join in!!
