If you're bottling right away, don't be afraid to sacrifice a little beer to avoid picking up the sediment. If you want to use the spigot on the bucket, that's fine, just open it slowly and drain the first pint or so into a glass (great for testing the gravity) or into the sink to avoid the little bit of sediment that may be disturbed by the moving fluid. But once you are in transfer mode be sure to avoid splashing by using a tube to gently move the beer into the bottling bucket.
If you're going to use a secondary (clearing) vessel, don't worry about the tiny bit of sediment as it will settle out in a few days. edit: but always, avoid splashing
