There are obvious negative effects of sugar, but really only on the heart. Your brain on sugar is much more hyper active. Your neurons fire faster, and cause messages to be sent quicker. The reason there is a crash after eating a lot of sugar is because of a waste product of your neurons firing. The waste product is called Adenosine.
Caffeine works by inhibiting Adenosine receptors which cause you to sleep. If you take sugar and caffeine together, you get hyper, with a slower crash rate than if you just had sugar.

Caffeine is a stimulant drug, which speeds up the synaptic connections in your brain, increasing reaction times. Nicotine, and Ecstasy do similar things, but are much more dangerous, and (in the case of ecstasy) illegal in most countries.
No, sugar and caffeine are two separate entities. Caffeine can keep you awake and make you hyper. Sugar is one of the fast body fuels but in excess it can add to your weight.
