Eric,

you may find this resistor calculator useful in deciding on the values you need,
according to how many LEDs you have and how they are set up, in series or parallel.

It will help you work out the minimum value for "safe" operation and, as Peter has suggested,
you can move up from there in deciding the brightness level you want.
