This is going to be a 'medium' level comprehensive guide to product photography equipment:

First thing first, the equipment you'll need to buy; you may find LOWER prices that what I'm showing here, but you do NOT need to pay more:
Sony A6000 - $650 : http://store.sony.com/-alpha-6000-mirrorless-interchangeable-lens-camera-zid27-ILCE6000//cat-27-catid-all-alpha-advanced-amateur?vva_ColorCode=BC008
30mm Macro - $280 : http://store.sony.com/e-30mm-f3.5-macro-e-mount-macro-lens-zid27-SEL30M35/cat-27-catid-All-Alpha-NEX-Lenses?_t=pfm%3Dsearch
Tripod - ~$50 -> $100
Ball-Head - ~$100
Lightbox - $70
Lamps - $50
Total: $1250
For your tripod and ballhead needs, I recommend Sirui.
What does this get you?
1: Product shots with a mostly white background. The lightbox with the lamps and possibly the tripod are needed for this.
2: Product shots in settings around the house. You will use your tripod and set a long exposure to get the correct brightness.
3: Macro shots. You can easily get shots where a keycap will fill 1/3 of the frame. You can get even closer, but it gets kinda awkward using a fullsize tripod pushed against the table where your subject is.
What will you need to learn?
You need to get comfortable using manual mode to make good use of your equipment and get professional looking shots.
You'll be using long exposures (1 to 5 seconds likely - but I don't actually know how dark your setting is) and medium apertures (around F8) on a tripod. But do NOT take these suggestions as gospel, you should still take the time to learn the exposure triangle. This isn't really hard though, the a6000 is a mirrorless camera (NOT a DSLR) and the screen and viewfinder are WYSIWYG; on a DSLR, your viewfinder shows what your eye sees, what the camera sensor sees is entirely different. Since this is technically a studio setting, keep your ISO at 100 to minimize noise.
Other accessories?:
Joby Gorillapod (table-top tripod) - used for tight spots such as under a table or for close-up 1:1 magnification shots.
Ring Light/Flash - adds a ringlight effect to the eyes of sculptures/dolls. Otherwise, it's handy for full macro shots, but you already have a gorillapod and can use a long exposure ; don't buy this, just save your money instead.
HVL-F32M Flash - This will allow you to more nimbly use your camera; you'll get proper exposure without needing to use your tripod, giving you faster setup/clean up times and better angles for your shots. Set your shutter speed to about 1/50, your aperture to your taste, and flash compensation to +0 (adjust and retake photos as necessary). Make sure it's pointed at the ceiling and you're good to go. This won't help you with macro shots of keycaps because the lens will be VERY close and block out light; you'd need a 50mm or 100mm macro lens before the flash can kick in.
EDIT:
Counter-point:
no one suggests using 30mm, why did you recommend it?
Answer:
Since this is a product photography usecase, it's convenient to be physically closer to your product, than you would be using a 50mm or 100mm lens, to readjust things.
Thanks for the thorough reply and recommendations. Everything points towards tripod/lightbox/learning combination.
