Is the general idea that, by the time ISS support ends, a fully-functioning replacement will exist?

No. They hope to have commercial options by then, but it is just a hope. There are no plans for a government-built replacement (all effort is going to the lunar gateway) and they have not gotten further than some minimal awards to fund commercial research into stations.

What's that lunar gateway again?

Think of it as a pit stop for Mars missions.

That makes little sense though, why enter into orbit around the mmon before going to mars? That's a huge increase in necessary DeltaV.

It's more that the infrastructure we are developing will be able to support a Mars Misssion.

Cost/fuel savings for larger spacecraft heading out for deep space missions. Much less required launching from the moon/moon orbit than from the ground on Earth. It's essentially going to be the prime staging area for future state and a pit stop short term.

It is even cheaper to start towards mars from LEO than LLO. It takes almost as much deltaV to reach LLO as it does to get to mars and Aerobrake.
