Hello Drinky.
Assuming that the factory mounted it right may be a bit risky. I would take an afternoon and check everything.
As for break-in, my Koetsu sounded very fine after just a few hours - it probably sounded that good at the outset, but it took my ears a few hours to catch up. According to the cartridge builder and rebuilder Soundsmith, the main reason why cartridges need time to break in, is because it takes time to twist their guts around to accommodate a poor setup.
As for records, consider anything you know well, especially an Angel 45RPM. Happy listening!
