Child Proofing: Advice needed :)

So, as my recent posts would clearly show, the need to child-proof has become sudden but imperative. Most of our "storage" furniture (think, TV cabinet, desk and their respective drawers etc) are low lying, it appears as though I should get shelves that suspend from the ceiling to keep our important documents (Josh's social security card was almost baby food yesterday) and other important electronics from being toys, or worse, food, for Aria. Anyone live in a slightly space-challenged apartment/home also inhabited by an incredibly active, albeit totally naive toddler and have brilliant way to keep everything organized and in one piece? Including said toddler...?
