My other concern is data backup, since theft is so rampant my thought was to buy a cheap assus 8 inch laptop, back it up to the hard disk and whenever possible upload the raw files to the internet (ha! i probably won't have electricity no idea where i'll find the internet).
This doesn't make sense. If thieves can steal your recorder/memory they might as well steal your laptop.
I say ditch the laptop idea if you're concerned with theft and lack of electricity. Buy a whole stack of cheap 2GB/4GB SD cards, they are $4.50/$6 each at newegg. After filling one up, post it back to US by registered mail.
If you really want to backup on location, get a USB stick type SD card reader, and bring it to an internet café. There's at least one internet place in every capital/major city, but don't expect upload speeds above 0,5mbit or so. Uploading might take a hours with intermittant dropouts.
Then again, crime in Africa is largely overexaggerated. Apart from the big cities (Joburg, Nairobi, Lagos, Kinshasa, Cairo etc) you're pretty safe:

A Church pre might be a good addition, but stock up on 9v batteries, they might be hard to find in the field.
You could also consider sending an R-09 to Chris Church and have the internal mics upgraded (Micskeeter mod). That gives you versatility to haul up the recorder from your pocket and tape anything on the fly.
I made six trips to Africa, taping in remote locations in places like Benin, Burkina Faso and Angola. I wouldn't gamble and buy rechargeables in-country. For sure there weren't any in Luanda last time I was there, and even less so in the other towns. The ex-pat stores are far inbetween, you might end up in a wild goose chase. Since you're on an assignment, you don't have all the time in the world to scout around, so I'd be safe and order a charger with the right voltage and plugs before you go. Plenty of them on ebay.
