Revisiting NIB v2, help getting started right please?

Hi all, we had MPSMv2 as our first printer, and it broke. I got a warranty replacement, and lent it to a friend who never used it. I’m getting it back and my son wants to fire it up again.

Hoping to get ideas on how to start for best results. Bed rewire out of the gate makes sense, but very intrigued by upgraded x-carriage/idler/fan etc that might make this perform closer to our Prusa Mini, maybe even add a Revo layer if we get it rocking well.

Can someone help ID this setup in the photo (will add below) and let me know your advice?

TIA!
