Though it's only a mile (20 min) walk from the ferry landing, the industrial scale of everything around you may not feel 'walkable', though half is along the water. It is definitely bikeable. Alameda Island has a lot of LimeBikes on it. In fact it looks like 6 of them are visiting Faction/St George Spirits/Hanger 1 Vodka now. And 6 are also at the ferry landing waiting to go join them.
I'm gonna say yes with a strong, it depends. Roy's answer is spot on and I'd like to add a few things. It is a mile but I consider that walkable so that may be personal preference. At least once a month I'll take the ferry home from the city, walk to Faction, then walk back and continue on to Oakland. This is where the it depends comes in. It's hard to get there FROM Oakland without going through SF. There are a couple times the ferry runs that way but it's at weird times. I usually take the bus there and ferry back. Coming from and returning to SF may actually be the easiest.
Not, ferry terminal is about mile away.
No, unfortunately no ferries takes you to where the brewery is. Would be awesome though!
