OK, I gave you some thoughts about lighting.

You should also think about what kind of tripod to get.

My advice on tripods is ... Don't overbuy.  (don't buy way more than you need).

It has to be able to hold the biggest camera you will use in the studio, but not too
heavy to use in the field.

I have a Bogen Manfrotto 3051 Tripod with 3047 3-Way Panhead with Quick
Release -- it's fine for studio work (big enough for a medium format camera, etc.)
... BUT that tripod is too heavy for field work.

For field work (hiking, landscape, ...) , I will be getting a Bogen - Manfrotto 3021BP
Pro Black Tripod Legs (Height 4.4 - 69.3", Maximum Load 13.30 lbs)

The tripod has an easily removed center column that just as easily re-fits as a
horizontal lateral arm. Not only does this allow the camera to be offset from leg
position, it provides the simplest way possible to shoot from directly overhead.

If you are going to be serious about macro work you may also want to have a
"Velbon Super Magnesium Slider, Macro Rail" -- this is a 2-way focusing adjuster:
left-right and also front-back vernier adjustment.

The combination of the Manfrotto 3021BP with the Velbon slider would give you
very good control over camera position (POV), composition, and focus -- that will
be essential for getting unique images of flowers, moss, lichen on the side of a boulder,  ...
