Hi Red Owl,
Saltwater is where distance really counts. To get distance you need high line speed. To accomplish that you need a faster action rod. If you are serious about saltwater fishing you need a rod designed for that type of fishing. Then you need to learn the double haul. The double haul is not hard it just takes some coordination between your two hands and the timing of your cast. You can practices with no rod in your hand. Most beginners move their line hand too far when they do the haul. You only need a short 6" haul to start. We all do it slightly different but the basic stroke is the same.
Your best bet is to line up some casting lessons. If that is not in the budget you need to buy a casting video. I learned from THE ESSENCE OF FLYCASTING By Mel Krieger. It may be a little dated but still good. The Lefty Kreh on Fly Casting would be a good DVD.
