For 15 Ghash/s you should set the worker share difficulty to 16.

Rule of thumb is about 1 diff per Ghash/s with power of 2 increments (2, 4, 8, 16, 32, 64, 128 etc). Actually the power of 2 thing is arbitrary and you are free to use a linear formula. Difficulty is generally* always an integer value.

If you set the difficulty too low, pools using auto-adjusting difficulty like BTC Guild will adjust it higher automatically shortly after your worker starts hashing, but it's better to adjust the starting difficulty with a reasonable value.

* I think some pools like Eligius use or have used non-integer difficulties
