I've 6 discus in a 66 gall tank with 20 cardinals, and 6 cory. i don't have a digital camera though....
I've plants in my tank, but it is loads easier to keep the tank clean if it's bare-bottomed and unplanted, or you just have bare bottom with plants in pots or floating plants. It kind of depends how small your discus are - the older and bigger they are, the easier it is to use a decorated tank, as they are not so finicky with water quality.
I had my tank running about 4 months before adding discus. Most people reckon a more mature tank is better as it is far more stable and there is a better growth of freindly bacteria etc.

Ahhhhhhh i am so so sorry i did not add my post but i have been up to my eyes in it making cards. I have a bit of time now hope i am not to late for you. I will post some photos as well.

because when the discus all follow each other the angels do the same! they are fine with each other and do not harm of scare the discus, try and get smaller ones. get two different ones from diff tanks or diff shops. personally there is no trouble keeping them together. some people say you shouldnt as many years ago discus carried a bactieria which angels coudnt live with but throughout breeding they can now. and infact discus and angels both come from the river amazon hope the info helps
