Hi there.. I agree with Darrell (Hillbilly).. he's given you some good advice. If I understand you this is a 72 gallon tank and you want to add 10-15 juvie discus and more than 11 cories and bns and angels... That's gonna be a lot of fish.. I would say as adults 7-8 are probably the right amount of discus for the tank plus a bn plus some cories if they can take the high temps of 84-86.. Yes you can add angels but as you noted they are eager eaters and may out compete the discus so I would not add them til the discus are at least 4-5 inches.. Whatever you add to a discus tank after the first discus are in... qt, qt, qt ...
The main reason for going BB is cleaning ease.. the cleaner the tank the healthier the discus.. You can certainly add some driftwood or pots or floating plants just realize that it just makes the cleaning a bit harder... so you have to judge how diligent you are gonna be.. a lot also depends on the size/age of the discus when you first get them... the smaller the more sensitive they are and the more work.. Once they hit 3 inches they are more resiliant than 2 inchers etc..
The bns are great for discus tanks.. they stay relatively small so there is a lot less poop than with most other plecos.. I like the albino version the best but there are several different types.
Good luck whatever you decide to do and lets see pics when you get setup. Sue
