I think your original description (minus the Chinese algae eaters and with 6-8 of the cories) has a good number of each of the fish you wanted, but has too may diifferent types of fish. I'd suggest looking up adult sizes of each of these things using Google, and then adding up the total inches for each group of fish you have. As examples,

8 zebra danios x 2" for each fish = 16" for the group
2 bristlenose catfish x 4" for each fish = 8" for the group

Then select your favorite of the groups you mentioned, and add up the inches for the groups, until your sum comes out to 60" or less. Or possibly a bit more, but if you put much more that 60" of fish in it won't be the best environment for your fish, and if something goes wrong it can go wrong much faster. Please note that 1 inch of fish per gallon of water leads to a tank that doesn't really have that many fish in it, compared with many tanks you see in pictures, or in many tanks in the shops.

Of course you can't add all at once! Using google again, rank all the groups you've decided to go for in terms of toughness. For example, zebra danios are really tough and are a good candidate for going in first. But panda cories are pretty fragile and should be put in much later. After each addition of groups, make sure your ammonia and nitrite levels are down to zero before adding the next group. That's what I would suggest!
