Salt water fishing setup

[specsaregood]

I want to get DW a whole salt water rig and tackle setup for her bday and I'm a noob on the topic. If it was lake/pond fishing I'd be fine as I spent plenty of time fishing freshwater; but she likes to fish off piers or beaches in the ocean and catch fish "you can actually eat".

If it matters, she likes fishing off piers best.

Anyways, anybody with such experience want to recommend somethings or best place to buy online? Starting from scratch...
