On standard spoking patterns, one crosses a spoke over the first spokes it crosses but under the last. This sort of "interlocks" spokes. I've always assumed this was to give the wheel more lateral strength by supporting each spoke against crossed spokes when under lateral load. It is obviously possible to lace a wheel without spokes touching - a radial laced wheel obviously does that. However, I think the key to your problem is your statement that "some spokes are less tight than others". The biggest key to a strong wheel is uniform spoke tension. This cannot be achieved that well on a dished rear wheel, but it should be possible to achieve fairly uniform tension on a front wheel. I'd try retensioning the spokes, aiming at tension as uniform as possible. With old wheels, it is sometimes best to untension all the spokes then retension all spokes at the same rate in realtively small increments. If some spokes are visibly worn from rubbing against one another, you can replace them before beginning to retension.
