I'd go with the 6lb for sure over the 20lb or 30lb. Those would be good for spinner baits though. Depending on the worms you have (4-6"), they could work great. Also, creature baits can be amazing too. Texas or Carolina rigs are perfect in the eel grass. Also, pick up some 3/8oz Warbait Slayer heads and 3-4" swimbaits.
If I was going Big Hammer I'd buy Sexy Smelt, Red Calico Hunter, and Rainbow Trout. Look those colors up on their
website Then go to some place like Dana Landing and buy whatever baits are similar or that just look good to you. Personally, I prefer and mostly use
Edge Flurries for Swimbaits. I like Greenback, Minnow Magic, and a bunch of others.
Also, I've been fishing Zman Paddlerz. But, I have no idea where to buy them except online. I use Tackle Warehouse. I use them on the 3/8oz Slayer head.
As far as walking the shore; Just find a stretch of beach that's long so you have lots of area to work and go from there. Maybe Fiesta Island as it has lots of shoreline and is easily accessible.
Hopefully this gives you an idea of where to start.
