In regards to lens mounted flash/ring/LED lights, yes, they can get you light where needed, but the photographic quality of front-lit subjects is typically poor (no modeling), more so when there's a ring or more than one light source, adding all kinds of weird specular highlights. Best to use available light with modifiers or off-axis flash/LED lights with or without modifiers to control the direction and overall "quality" of light.
Like @Photopilot said, macro photography takes special dedication and equipment.
So does photographing people on stage from a distance. To get close-ups in that scenario is very different from macro/close-up photography, which is the title of this thread. "On stage" photography has it's own set of difficulties, technically and socially, as you want to be as unobtrusive as possible, being virtually invisible.
A prime lens there can give you the advantages of a larger aperture, but if your distance to the subjects is restricted, you are limited to the framing/composition it gives you from that viewpoint. A zoom has much more flexibility on framing and thus composition, alas with a 1-2 stop penalty on aperture, which also limits you from isolating your subject by selective focusing and shallow depth of field at its widest opening. So that's a choice to make.
Regarding kit lenses, I've found most to be mediocre, and of limited use. Better spend money on something in the range and performance qualities YOU want, not the camera manufacturer.
Beginner classes can be helpful if they really teach you camera handling, settings, and typical use. It all depends on the teacher. On the other side, there is tons of information available on the web, which can be more useful, and dedicated to your specific uses.
On a side note, 2 weeks ago I was handling a Canon M (video) camera on a nice portable rig using a beautiful 100mm (or 150mm) f/1.5 prime lens (non-Canon brand). What a dream that was!
