Swarm on Route 203. Check the TV or ask Dawn/Lucas' sister in Sangem Town and they'll tell you if there is a swarm at that point.
You can get it by talking to Dawn/ Lucas's sister in Pearl or Diamond. Each day they tell you a different species of Pokemon is swarming, and where to find it. The Pokemon changes each day, so Cubone will eventually be swarming, if it isn't today.
You have to trade a Cubone from Leaf Green or Fire Red.

Yes, Cubone does evolve. You can get it at Route 203 in Pokemon Pearl or Diamond. It only appears to be here if it is swarming in the area. It evolves at 28.

Cubone can be found in the Pokemon Tower (aka Lavender Tower) in Lavender Town. There is a 5%-14% of finding a cubone depending on which floor you are on. 24 is the highest level that you will find them. In the Japanese version of Pokemon blue, cubone can only be obtained through trading.
