The gain of a non-inverting op amp
The non inverting amplifier setup they are describing looks like this:

You need to calculate the value of R3. 

When they talk about "what range of outputs would you expect", they are talking about the output with V1 == 0V. That is not 100% clear in the problem description. 

So given that, you should be able to calculate the output offset voltage from the bias and offset currents (assume different signs of the offset to get a range). The rest of the problem should be self-explanatory.
