If your suit is a fairly new or well fitting open cell 5 mil, yeah you'll be OK for as long as you'll be working on getting out there and then figuring out the abalone thing. I'm a 7 mil kinda guy and have been seen in a 9 a few times as well. In 35 years it's been 60 once or twice. Right about now it's 54, down from the 58 I was just enjoying in So Cal.
There are halibut in the Ft Bragg area, but as this will be your first time, I'd recommend you get online and look at the campsites in the area like Salt Point, along with small places like Stillwater Cove Ranch, Timber Cove Inn and the Gualala Hotel if you get up that far. Mendocino and Ft Bragg-wise, there are many places to camp, like Russian Gulch, MacKerricher and Albion. There are a bunch of low dollar places to stay as well if you look hard.
You'll need a license, all your gear, a float with a line on it to clip to the kelp, goddie bag, stringer and a small gun, such as a JBL Custom or a 50-70 cm euro gun.
Places to try will include Stillwater, Ocean and Fisk Mill Coves in Sonoma County. Mendo opens up with a load of places but try just to the north of the main cove at Russian Gulch.
