Been reading the links here about Saltwater rods/reels..now my head is really spinning ( no pun intended)..what i`m looking for is a good all purpose rod/reel to cut my teeth on..most if not all my rods/reels are fresh water and some can be used for saltwater for light inshore like my calcutta 200gtb,Abu  Ambass. 5600c4 and 6500c4 and Okuma connvector cv15 D  do I need to beef things up for say halibut,salmon.Lings etc etc same with rods ..hope my question make sense..Thanks

The reels you mentioned are plenty capable. You need heavier gear for salmon trolling but for just about everything else you should be fine.

Freshwater bass rods work great in the salt. You can mooch for salmon, jig shallow water for rockfish and drift live bait for halibut with no problem.

Tie good knots, use decent line, set the drag right and you are good to go.

When first starting out in the salt kayak fishing, it's a good idea to just use inexpensive gear, something that won't make you sick to your stomach if it falls overboard or gets broken or ruined with sand in a surf wipeout. A lot of people start with an ugly stick and an old Penn reel, just somethingto think about, Cameron

Seems like a lot of the reels you mentioned would work for most fish you would like to target, with the exception of salmon trolling as Otter mentioned already.  Those abu c4's should be able to handle lings, halibut, and salmon mooching just fine.

Ugly stick tiger rod with a shimano tr 200 is my all around set up has caught rockfish halibut and one 48 pound sea bass. Had this setup for 6 years of yak fishing in my opinion best bang for your buck. For salt
