As your lenses are from the 1970's they could be PreAI or AI.
DO NOT attempt to use PreAI as they will damage the meter prong.
If they are AI then they will meter with the D300s once they are programmed in. The D300s will allow programming of up to ten AI or AIs lenses.
I think it would be well worth your while looking at a thread I did in the Lens Forum - The Ins and Outs of the Nikon Mount, as that should answer all your questions.
