Don't know how long you will be up for but if your new I would suggest booking a Charter for the early part of your stay.
That would cut your learning curve and make the rest of your stay a lot more productive and enjoyable.
Gearing up to cover all the different presentations is very expensive.
Your riggers will get your lures to the required depth and take fish, period.
If you wanted to add a new presentation, by fishing with an expert you would see what to buy and take the guess work out of the equation.
All the shops in the area will stock everything you would want to add.
Best of luck.
