Hi Rico,
I would suggest that you get hold of a 7' spinning rod, in a medium action. The reel in a size 2 or 3 also spinning, with a good front drag system and instant anti reverse also must be saltwater resistant. the rod must be good, for using braided line.
I prefer to use braided line as it is thinner than mono and more abrasion resistant too. It also has less stretch, for better bite detection and giving your lure a better action, use the braid with flourocarbon leader, tie it on with a five turn surgion to the braid and make your leader about 60cm long. You sould also try to use 10lbs to 14 lbs Fireline, your knot sould not pass threw your line guides.
Jig head size 1/8oz, 1/4oz to 1/2oz, and in hook sizes from 4 to 1/0.
Soft bait jerkshads 5", minnows in 3",4" and some Berkley CAMO worm and your all set.
Then get your prefered soft bait on the hook, cast out. Try differant retreives and cover ground and your bound to get something, then you just hold on tight.
