I think its safe to say they can forget about retaking crimea. They can negotiate the rest of their territory back though.
I'm skeptical that the two can be separated in the Russian war aims. It seems more likely that if any territory is recoverable piecemeal, it would be the hard-to-resupply peninsula vs the areas with a direct land connection to Russia.

That they do. Losing ships to a country without a navy is wild.
