Getting the best sound quality

I have the "Snowflake" microphone (which I absolutely love!) and it has really upped the sound quality when I record into Garageband. I was just wondering if anyone was familiar with this product and knew of a good setting to clean up audio recorded with the snowflake? Or in Logic?

Thanks!

What instruments are recording? (mostly)

Mainly vocals and occasionally piano (grand and upright), acoustic guitar and thumb piano.
