At this time we do not offer a 'bundle' option for the 29 Gal. AquaSprouts Garden. You'll need to procure any gravel/décor you want to add to the tank, and, of course, fish, fish food, and water conditioner or a source of dechlorinated water. A grow light is optional but greatly expands the range of plants you can successfully grow.
There are a couple optional items that might improve your experience. A supplemental aerator is a nice failsafe, but not required; we like to add an undergravel filter. If you're going to be setting up in an environment that runs cold or isn't climate controlled, you might want a tank heater. Most aquarium fish are tropical and require a fairly narrow, warm temperature range, but you can also select more adaptable fish like platies, mollies or common goldfish.
