Glad to hear you are lining up a trip. I'm hoping to go back in 2012 also. I've got some revenge to administer on a kudu...
Don't forget chapstick and sunscreen. I went in September and man was it dry. Really had to watch yourself or you'd get burnt quick.
As far as clothes. I ended up wearing some green carhartt jeans. Bought them at a local farm and home store. Comfortable and pretty durable in all the brush. And for boots I just wore my well broke in Justin lace-up ropers. I did have to get a few new shirts but other than that, kept the clothes budget pretty light and used what I had on hand.
