The first time that I saw darts in real life was at an aquarium as well. I remember feeling just as you feel now, blown away by the fact that they are real and that they can even be kept in captivity. You are doing exactly the right thing right now: research. The more you learn in advance to getting the frogs the better off you and the frogs will be.
A 75 gallon aquarium gives you a lot of room to play around with terrarium design. In all honesty a 75 might not be the best way to start out. A larger terrarium is more work to maintain and is if mistakes happen they will be financially larger than if you start with a smaller 15-30 gallon aquarium. If you do choose to use the 75 gallon aquarium be prepared to raise the frogs that you purchase in small tanks first to make sure that they are large enough to handle finding food in a large terrarium.
Next to having the propper enviornment for the frogs, having a constant source of small insects availible at all times is the most important thing. Flightless fruit flies and 3 day old crickets are the most common feeders availible. Setup fruit fly cultures a good 2 weeks in advance to purchasing the frogs and make sure you have a reliable pet store or cricket breeder to buy or order very small crickets from. Other food items to look into are rice flower beatles, springtails and termites.
Keep learning as much as you can about them and things should go smoothly. If you have specific questions in the future feel free to ask. Good luck,
