Hi SimonF,
Choose a car that is adapted to kenyan road, do not import a saloon car and make sure that spare parts are available here.
By law, you can not do it alone and must go through a freight company that will deal with everything (freight forwarding, clearance in the sea port, payment of duties, registration) but you must follow it up.
Aks about the importation cost, make sure that keys are left in the car so that your car is not stuck at the port, put your car in the container if possible (better than boat deck), and do not forget to harass the freight company to know the date of arrival at the port, prepare the papers in advance, go to Mombasa yourself to get the car.
It is preferable you come with previous paper such as logbook or crossing book to easily cross borders. If the car is imported with crossing book, go to Mombasa with 100 USD to have temporarily permit, equivalent to road licence. Disadvantage, you are paying high prices for parks/reserves and car will be difficult to sale.
For registration, get the following documents to the Registrar of Motor Vehicles at Times Towers (Haile Selassie Avenue) :
- Duty and VAT receipts
- Import Entry form (form C63)
- Foreign Log book
- Port Release Order
- Bill of Lading or Airway Bill
- Clean Report of Findings (CRF)
- Import Declaration Form (IDF)
- Authority to enter goods for home use for Customs Commissioner & Excise
- Vehicle Inspection Report (VIR) (if car is for commercial use)
- A temporary Importation Document (form C44A or C44)
- Road Manifest or Crossing book for car imported by road
- Foreign Vehicle Receipt/License
- Personal Identification Certificate Number (PIN) card
- Certified copy of Identity card of the owner of the car or Passport
- Insurance cover
- Formulaire A signed by importator
Good luck !!!

There tons of second hand for sale in Nairobi, many small RAV or small 4x4, so you can buy a cheap one and sale it when you go. Otherwise, good or new cars are expensive.

Driving to SA, many are doing this... Zimbabwe is a bit problematic and make sure you have a extinguisher and danger sign in your car (required by Tanzanian law)

For the 2-bedroomed apartment, you should not have any problem. Nairobi is full of empty apartments so prices have plummeted (anyway they were too high).
Popular areas that offers good quality apartments near City centre are Kilimani, Lavington, Upper Hill. Otherwise, there is also Parklands and Westlands. And prices should be between 30,000 to 60,000 Kshs (app. 300 to 600 euros) depending it is furnished or not, if there is a swimming pool, satellite TV and/or gym. Then, another option is to go for bungalows or guest houses in poach area such as Karen or Muthaiga districts, there are far from City centre but very nice with plenty of trees. This is also another cheap option.
Don't forget that a 2 to 3 months deposit is usually required as per contract and that many (bad) landlords have the bad habit to keep it when you are leaving (so do not spoil the paint and take picture of the place when you move in).
Lastly, always ask about water (availability and pressure). You don't want to move in a place that has water once a week !!
To discover Nairobi, you can always have a look at Google Map Kenya which is brand new (launched in June) and very detailed.
