No problem Lewis, I'm glad that you are going to be getting some modeling use out of MoI - that's actually more the main thing that it's designed to do! :)
For the right project, especially mechanical stuff you can gain a tremendous amount of speed from using MoI instead of polygon modeling. But for other projects like things that are organic characters those are better off done with polygons.
The main workflow for NURBS modeling is very different from polygon modeling (but that's why it's a useful companion because it has different strengths and weaknesses), you want to use 2D curves to define things with some curves building base parts and other curves being used as cutting objects in boolean operations. Booleans are the primary way of modeling things in NURBS, that's the biggest difference from polygon modeling. Anything that has a structure like machine cut stuff is a great fit for boolean NURBS modeling.
One of the things that can tend to be hardest for a poly modeler to get used to is the idea of building extended pieces and then using cutting operations to form the final edges, a lot of times polygon modelers have a strong tendency to want to draw in all the final edges and then try to build patches between them to fill them in - but usually that's not the best strategy - instead you want to build simple stock pieces which may be extended and then cut them with a boolean if needed.
There is some previous discussion here on some examples of this and tips for poly modelers, you may want to read these:
