I want to shoot video with my af and af-d lenses and change apertures during the process. Will manually changing apertures via the aperture ring allow a change in f/stop while shooting video? What custom function do I need to set to enable the aperture ring? I plan to use my 35 f2 D and 85 f1.4 D lenses this way if it'll work.
The dSLRs do not support the aperture ring. If you have a lens with an aperture ring, you need to lock it at the largest f- stop number or smallest aperture. The lens also needs to have a control chip in the lens.
The dSLRs use the chip and command dials and not the aperture ring.
If you have an aperture ring without any chips then you need to open the lens iris as large as possible, the smallest f-stop number. Set the exposure time and note the aperture setting displayed by the camera. Now you set the aperture ring to the f-stop number displayed and take your shot.

That is not true as a general statement.
The higher-end Nikon DSLR's (including the D300s) do offer the option of using the lens' aperture ring rather than the camera's command dial. This is controlled by one of the Custom Settings (on the D300 it is f7, I'm not sure which it is on the D300s).
Note: I never used a D300s for video, so I don't know for sure whether using this setting will allow one to alter the aperture during recording.
Are you QUITE sure about this? Because I believe I've done this on a great many occasions for filmmaking purposes.

Note that you do not have to change the CSM setting to use the aperture ring with MF lenses. The setting only applies to AF (CPU) lenses with aperture rings because there is a choice between using the command dial or the aperture ring to set aperture.
There is one quirk of using the aperture ring with the D300, I don't know if it is also the case with a D300s. LiveView will not work with AF lenses that have aperture rings, if the aperture ring is enabled. The aperture ring on manual focus lenses works fine with with LiveView, but AF lenses must be used with the aperture ring disabled for LiveView.

Gary, more good info. I've been testing with a 35 f2 ai lens changing apertures and focsing manually. I like the effec of aperture changes Once problem I've run into is the sound of the aperture ring changing apertures is picked up in the video.
