The closer the fingers are, the more economized the motion. Finger independance is very important as well. Here's a simple excercise that will help you out with that.

|-8-7-6-5----------------------------------------------------------------------|
|------------8-7-6-5-----------------------------------------------------------|
|-----------------------8-7-6-5------------------------------------------------|
|----------------------------------8-7-6-5-------------------------------------|
|---------------------------------------------8-7-6-5--------------------------|
|--------------------------------------------------------8-7-6-5---------------|

Looks like a simple chromatic excercise right? Pretty much, but here's the catch. you move each finger independantly, keeping the others on thier appointed frets. Hope this helps
