Michael,
Glad to hear you have decided to try Africa. The species that you have listed are readily available in many areas of South Africa and I can tell you from my experiences in the country that it is a very friendly, stable, and beautiful place to visit. I have been to SA twice in the past two years and have my third trip planed for June of next year to the Eastern Cape. The area I hunt is extremly rich in game and it is not uncommon to see 8-10 species a day.
All the animals on your list can be hunted in the Eastern Cape, however, as Grayghost noted, the Kudu we hunt there are the smaller Eastern Cape variety. If I may, I would recommend that you also consider hunting a bushbuck when you go. These spiral horns are extremly wary, hang out in some of the most challenging terrain, and are truly a challenge to take. They are number one on my list next year.
Feel free to drop me an email if you would like and I will be happy to share some of my experiences or just talk African hunting with you. One thing is for sure, once you go, you will return.
