There is a style of playing referred to as Shash Spread. It is the best method of playing.
With your left hand, put your index on the down arrow, and your middle on the left arrow. With your right hand, put your index on the 8 key on the number pad, and your middle on the 6. They will work as arrows when playing.
Doing this both improves your learning time, and will keep your wrists and hands from cramping as easily, as they are spread out.
Anyone who says otherwise is not as good as me, so they need to shut up.

You're gonna make a lot of friends with those pics...heh...

haha, im not as good at most ppl, but i can give u a few tips ^^
1: when u hit the arrow u want it 2 be as close 2 touching the edge as possible, if ur timing is right u should start noticing a rise in average perfects ^^
2: try expirementing with different play styles, find the 1 that best works 4 u ^^ mines 3-fingered(right hand index finger on the left key, down and up arrows covered by the middle finger, and right arrow key covered by the ring finger)

best tip i could give you is dont use the arrows. look up one of the posts about changing your buttons around. also look up ' spread '. play that style.
