As far as I know Jebo and Aqua One filters work the same way and are very similar in looks. I love my Jebos and have heard good things about the Aqua One as well.
I know it is personal preference, but why would you want to use blue gravel in a tank? To my way of thinking it isn't natural and detracts from the fish and plants which should be the main feature. Dark gravel is best as the fish are more comfortable and show up their colours a lot more. I can't help you with your bulk question sorry.
Do you really want a tank that comes with stand? Have you thought of making your own stand, or using existing furniture? This can be a lot cheaper and the money saved can be spent on more fish
