Bonnie already formed as a tropical storm (they are not named until they reach that status) and struggled as she crossed southern Florida. Current predictions are that she will continue to have trouble getting organized due to a relatively unfavorable environment in the Gulf, and she'll likely remain around tropical depression or weak tropical storm strength as she moves towards Louisiana.
There is no lower limit for tropical depression winds, which go up to 38 mph.

No, a hurricane does not start as a tropical depression. A hurricane forms from a tropical cyclone, which originates as a tropical depression. Tropical depressions are the first stage of a developing tropical system, followed by tropical storms and then hurricanes if conditions are favorable.
No. A tropical depression is a tropical cyclone with winds under 39 mph. A tropical storm is a tropical cyclone with winds from 39 mph to 73 mph.
A tropical depression becomes a tropical storm when sustained winds reach or exceed 39 mph.
A tropical depression is more organized than a tropical disturbance. It has a closed circulation and a definite center of rotation, which a disturbance lacks.
There are currently no active tropical depressions. Also, tropical depressions are given numbers, not names. The next one in the Atlantic will be Tropical Depression Fourteen. There is however, a tropical disturbance labeled 95L that has a high chance of becoming a tropical depression.
