Hi there Bantyhen, can I suggest you start by reading all the thread posted by Duncan (yelvertoft) above, it has links in it and I suggest you follow those. I think this is one of the best pieces of advise on this question you will find anywhere. From a personal point of view, I would suggest the D300s and the Nikon 18-200 VRII as a starter kit. It may well be that you never buy anything else and that this will cover all your photographic needs for years to come. If you do get bitten by the bug then this is also an up to date semi pro body that will last you a long time, do not forget manufacturers upgrade their bodies every 18 months to two years. It may well be overkill for you now and you may never move out of program/automatic mode but the D300s has the capability of growing with you as you develop your skills. Never forget that it is the photographer who makes the pictures, NOT the camera. Also, if in future you wish to expand your horizons, ALWAYS buy the best lenses you can afford. Bodies change regularly - lenses can last for years - I'm using some 30 year old ones that cannot be beaten even today.
As for question C - you seem to have done quite a bit of research and for me you are on the right lines. A portrait lens is usually from 85 mm to 105 mm so I would drop the 50 1.8/1.4 - I have one, rarely use it. Your 18-200 covers this focal length anyway. I think you may find that the 18-200 is your walk about lens, when I had a D300 and D2x it was the lens I always had with me on one body. For wildlife 300 mm is probably the shortest you can get away with in good conditions. I use an old 500 mm f4P Nikkor. For the Landscape the Sigma 10-20 or the new Tamron 10 - 24 take some beating. There is also a new Tamron 18-270 which I would look at instead of the 18-200 and 70 -300 as the one lens more or less replaces both of the others.
