At what spacing should I drill the holes? Every 18 inches?

I use brown plugs with 5mm screws going at least 50mm into the wall,
avoiding mortar lines. Every 18 inches sounds fine. I usually put 5 or 6
in
spread evenly, ensuring they are approximately in the middle of a
brick/block, to avoid damage.
