You risk back siphonage from the dishwasher. Check the installation recommendations for your particular machine, but it is generally easy enough to overcome.
Sure. Disposals install directly into the drain line, they're part of it. You still need a P-trap downstream of it but that's all.
Dishwashers usually dump directly into the tailpiece of a sink's drain lines. It isn't an air gap per se, but an air break - similar in function but different in construction.

Although it can be done safely if done right often local codes are requiring an air gap.
