DKC3 really only added Bear Coins and Banana Birds.
The Brothers Bear trading quest was just an extension of the bear coins. That's like docking points from OoT because it had eye drops and saws in your inventory in service of Biggoron.
And the Banana birds were always confined to the relatively small world map, with a single bird per individual world hub.
The cogs were simply end of level "rewards" from Krematoa, a plot device to fight the final boss.
The skis and patch from world bosses were again just plot devices in service of moving you to the next world. It's not really a collectible if it's mandetory to progress. It's just a reskinned key.

4 things you had to actively go out of your way to grab.
Overrated, just like the moaning and agonizing over DK64.
