Let's get those memories down to Long Term is an informal way of saying Let's send those memories to Long Term.
This is a typical way of communicating in a company or organization. It comes from a time when a department of a company would send documents to a different department on a different floor of an office building. It's typical to hear phrases like get this up to or get this down to when referring to inter-departmental communications. The movie treats the human body as a company of sorts, with different departments. It makes sense that the different parts of the body would communicate in a way similar to a corporate office.
I believe this sentence means "Let's store these memories in our long term memory", i.e. let's treasure today's events and remember them for a long time.
