Some things to think about:
- How long will you be gone?
- Africa's a big Continent, where are you going specifically? (What are your available resources, environment, and expected durations at each stay.)
- Are you expected to cover everything with the $3K? (This includes vaccinations, lodging, food, airfare, gratuities, etc.)
- What will be your power/electrical needs? (Will you be able to recharge your batteries? and how long between planned stops with electricity? What are their power sources? i.e. - 110/220, or/and most likely generator/solar power driven.
- Will you then be required to provide your own source of regeneration? (Depending on the answers to the above.)
- How will you be traveling once in country? Would a soft case be better than a hard? Or, would a backpack be better suited?
- Can you purchase items used, off ebay?
- Sticks can be the most important/expensive part of all your equipment needs. I would imagine portability would be key, and so you might want to go with only one tripod. {I'm attaching a link to assist with learning to shoot without one, if needed.}

- As for specific equipment... not really up to date on the consumer market, so I can only suggest you take others advice. Here are a couple of links to reviews:
