    Most recommend pruning lilacs right after they bloom. Most flowering shrubs bloom more vigorously on young wood compared to older branches. Cut 1/4 to 1/3 of the oldest branches to the ground each year. Lilacs often have many suckers/shoots coming up the middle. Remove any that aren't at least pencil width and those that crowd each other. Allowing room for air and light to move easily through the bush results in a healthier plant.

    Yes, I do believe that you are correct. You can, either, purchase a white variety, or you can take a cutting, and propagate an exact copy of this one.

    Lilac bacterial blight is one possibility. Being newly transplanted, the shrub is under stress and more likely to suffer from disease. Immediately remove affected leaves and stems and do not compost them. Prune your shrub so that air flow is good; i.e. don't let all the suckers grow and leave the shrub crowded. This also helps prevent powdery mildew which is common on lilac. Here is a gallery of photos of different leaf diseases. Research lilac bacterial blight and compare to these photos. Your local extension service may have an online or in-person plant clinic. https://www.extension.umn.edu/garden/yard-garden/trees-shrubs/management-of-leaf-spot-diseases/

    Powdery mildew strikes lilacs during hot, dry weather. Your bigger problem is going to be salt spray and possibly high salt soils. Lilac does not tolerate salt. Every state extension service puts out a list of salt-tolerant plants. Here is the list from Virginia:
