Dave,
When working on your long game gapping, remember you don't want to create too large of a gap between clubs (15-20 yards). You also want to make sure that when deciding between hybrids and fairway metals, that you consider which models offer you the the best playable trajectory into greens. Many players also feel more comfortable playing hybrids over fairway metals, because if the length of the club and the versatility. Others may feel more comfortable and consistent playing fairway metals for their forgiveness. Trying both types of clubs with a Club Fitter will allow you to determine the best model.
