Just booked 1st African hunt. Any pointers?

[madmurph]

I recently booked my first trip to Africa. I will be hunting South Africa in May 2008 for kudu, impala, blesubuck, springbuck, bushbuck, warthog, zebra, and blue wildebeest. I will also take a baboon and a duiker as "opprotunity" animals if I get the chance.
As a first timer, I'm just looking for some advice from those of you who have been there. Anything from travel tips, items to bring that one wouldn't normally think of, etc. Any help would be appreciated.
