The EJ are, as one would think, on the east side of the harbor entrance. I've fished there a couple of times and had a blast. We parked on Gulf Shore drive near the middle of the road between Durango and the dead end at the marina or whatever it is. There's a trail that goes south to the beach, it initially goes alongside a tennis court.
Looks like you can also park along Sunflower Ct between Melrose and Rosalie NE of jetty. That's a shorter walk than Gulf Shore Dr. The sand is soft and it takes some effort to slog thru it.
I've also done well walking the beach and fishing the bridge pillars on the west side of the 98 bridge. Parking on south side of the road.
As for the canals, I fish 'em just like I was bass fishing. Super flukes and road runners with twin tail trailer. I never subject myself to the hassle and expense of live bait but still do well fishing my confidence baits.
I don't like country music, but I don't mean to denigrate those who do. And for the people who like country music, denigrate means 'put down'.
