The crystal can be use up to 16MHz & capacitors should be 12 to 22 pF

Atmega32L - 8PU can run at a maximum frequency of 8Mhz while the Atmega 32 - 16PU can run at a maximum frequency of 16Mhz. For capacitor values refer datasheet.

If you are using one of the 'built in' frequencies then you can get away without using a crystal. The $50 robot does this with other ATmegas.
