When naming the coordinate compound Fe(CO)5, I was surprised to find the name was pentacarbonyliron as opposed to pentacarbonylferrate. Why is this the case?

I think both ways are fine because in Lavelle's green workbook, one of the questions involved Cu, and then the answer said you could use cuprate or copper. If you want reference, it's question number 9 from the Fall 2013 quiz for quiz 3.

My TA explained that you use iron when the compound does not have an overall charge. However, when the compound has an overall charge of 1- or any other negative charge you would use ferrate to account for the negative charge.
