I am completely confused about naming the coordinate compounds.
Do we need to know the latin names for all of the transition metals?
What is the order in which we put the different ligands before the ion?
Thanks in advance for your help.

Re: So lost on the naming
I'm not sure what you mean by "latin names" for the transition metals, but we are required to know how to name the ligands that bond with the central metal atom. You can review the table on page 117 for this.
In a sense, it's similar to naming anions (e.g. chlorine --> chloride) but--since we're dealing with TM complexes--the "-ide" ending will not be used. The root will be retained (e.g. chlor) and the ending "-o" will be added to the end.
Typically, the convention for TM complex nomenclature wants us to put the ligands in alphabetical order before the metal ion (and then the roman numeral).
Hopefully this cleared some things!

My TA, Jackie, said we should know the common ones, such as ferrous for iron. I'm guessing the transition elements with Latin names as part of the symbol (eg. Iron's symbol is Fe, latin name is Fe) would be the "common" ones we should know.

Just in case, although we do not need to know the Latin names, I would remember the important ones, or the ones that are used most often. Otherwise, it will most likely be given.
Re: So lost on the naming
The important information you get from the latin name is the oxidation state of the transition metal. If you feel comfortable determining the oxidation state of the metal, you shouldn't have to worry too much about the latin names.
Also, for naming the coordination compounds, it's crucial to be familiar with the list of ligands in the course reader. And, adding on to the naming format, when we order the ligands alphabetically, we do it based on only the name of the ligand, and not any prefix (di, tri, tetra, etc.) that might be before it.
