That's some mighty big reels you have there. I assume you are rock fishing since you mentioned getting snags.
Need to know the length of your rod.....on the blank near the grips should be some information regarding this. It should tell you the length and the line capacity. The reel you are using, over-head or egg beater and number aka 4500, 6000, etc
As for your target fish.
Salmons and Kings are mostly top feeders so you should be rigging up with a float to keep your bait close to the surface, which will also prevent your snags.
Snappers will occasionally come up to get a feed but bottom bashing is better for those, rig your sinker below your hook so you don't snag as much. I usually catch my snappers from the rocks on Yakka flies
Jews......heh the holy grail, these bad boys are caught with patience and more patience...unless you are a lucky SOB.
My advice, get a hook tying book that shows you the basic rigs and you work from there. The best way to succeed at fishing is to know your rig, know your fish, and practice
