Clock speed and writing to internal EEPROM.

I'm using the MC9S08EL32.

I've got two questions:

1.  To get the fastest processing, should I use the internal oscillator or an external crystal?

2.  My program is stored in onboard flash and we now want to store a couple dozen bytes of data.  How do I read/write data to the internal eeprom? Is there a published routine for this?
