Go in this order:

1. Thumb
2. Ring Finger
3. Middle Finger

And then try a simple arpeggio, like this:

E|-----------
B|-----3-----
G|--------0--
D|-----------
A|-----------
E|--3--------

From there, just keep running through patterns like that, with your fingers in that order. Thumb - Ring - Middle

That's what I've found to be the most efficient and effective.
