I use my SB800 with my D700 and D4 indoor (bounced and GF Cloudy) and as a filled flash for outdoorshots. Would it be ok to just leave my menu setting at 1/250s Auto FP for both indoor and outdoor flash use?
Hi Mel, I have left my D200 set at Auto FP for the last two or three years and virtually "forgotten" about it. As I understand it the Auto FP will only come into play outdoors in bright light conditions where the shutter speed may exceed 1/250 and fill flash is required.

Yes. That's what I and all of the pros I worked with always did.
This has the added benefit of protecting from over exposure when transitioning between indoor flash photography and outdoor. Many a photographer who shoots flash in Camera A mode indoors, has forgotten to switch to P or S mode when moving outdoors to shoot fill flash, but the flash is in regular sync. In Regular Sync mode, it will prevent the shutter speed from going above Flash Sync Speed (1/250th in your case) and if you select a wide aperture to blur the background you will cause horrible overexposure. Selecting FP Sync allows the shutter to go to whatever speed it needs to to produce a correct exposure from the ambient light. Then, you can safely blur the background with a wide aperture.
In addition, most pros use TTL-BL when shooting fill flash. Of course, for TTL-BL to work properly, the camera meter must be centered. This is why many professionals use Camera A, S, or P when shooting FP Sync fill flash, so the camera will automatically center the meter.
Here is a picture I took of my granddaughter at the pumpkin patch this week. As you can see, it was a sunny day and the sun was at camera's right side. Too much filled, not enough filled or just right?
The image was shot with my D4, 24-70mm f/2.8, and SB800.
Aperture priority, f2.8, 1/1250s, TTL-BL, and -1.0 comp on the flash, Maxtrix, ISO 100.
