Whatever seating stem you have should work. The Lyman M die is a good recommendation. IMO the normal expander dies are great for jacketed bullets or plated bullets, but using the slightly larger Lyman M die will help expand the case a bit more to accommodate the larger diameter lead bullets. FWIW most of the swaged HBWC bullets I've measured are around .359/.360 in diameter. That is the one extra piece of equipment that might be worth buying before you begin reloading.
I have shot many thousands of .38 Special rounds including thousands of DEWC and HBWC through revolvers and a semi-auto S&W 52, not once have I trimmed a 38 case.
As a new reloader I would just start with getting the press setup and knocking out a few rounds. All the extra stuff is a unnecessary distraction.
