Can I import a STEP file into TC 2015?  What is the easiest way, if possible?

No can do natively, but if they're not in the tens of Mbs, I'll convert one or two to TC surface for you.  Open-source FreeCAD will read .stp and convert to .obj or .stl, which are Deluxe-able, I think

Thanks for the info.  They are pretty big files, I would assume.  I will try the "Free CAD"  and see if that will work.  I am just trying to copy and past some components into my drawings.  Easier than drawing them myself.  But, I might have to.
