Use the fit calculator on the product web page.

Should give a general idea. Generally, however, it's sometimes not too bad to go a size down (or even sometimes a size up).
Many cyclists (adhering to the N+1 rule) ride a range of sizes anyway.
If you REALLY want to be sure, you can go to a Local Bike Shop (LBS) for a fitting, but those can sometimes cost, depending on the system used.

Amazon page quotes shipping weight of 25 pounds. For this setup, however, I would have expect around 30 - 32 lbs for the complete bike. EDIT: Although, I would if I really had to guess, I'd guess right at 28. . . about the same as the Insight, but add a suspension fork and wider (read: heavier). tires.
Entry level hybrids and 29ers are not the domain of weight weeinies, anyway. Besides, like we always say: it's the rider, not the bike.

Walmart and other "big box" stores: Generally sell the same size frame for all bikes so the only differing characteristic is wheel size: which, is fine (and pretty much the standard for children and youth bikes).
Wheel size on this particular beast is 700c. This is basically the standard "road" rim diameter and corresponds, as pointed out previously, to roughly a " 29" " wheel size when including tire height.
