So, you have a small dilithium fortune there. use that. i havent calculaed exactly but that looks like more than 150,000 dilithium to me.
Which is close to 1,000 Zen, or $10 worth in the current Zen crash; more when the price goes back up, which it will.
As for equipping other ships; I personally never buy duplicate equipment. I'll keep equipment for differing loadouts (beams vs. cannons), but you can't fly two ships at once, and every place you can switch ships you can swap gear, so why have something sitting in a ship doing nothing? I use my ships as bank slots for alternate gear, nothing more, unless I'm flying that one.
