Is there a way to calculate/estimate how big a sample from a parent distribution would need to be for the distribution of the mean of that sample to be approximately normally distributed?

You can't just calculate it, it depends on the distribution of the data. But about 30 is the rule of thumb.

The BerryEsseen theorem may be useful here.
