Deepak, looks like your settings are quite OK. What I like most of my NA is the timbre accuracy. On well recorded voices the thing is just astonishing. I hope you enjoy it a lot I don't have any complains about its tracking, but my current cart is a Shelter and I don't listen to many 45rpm discs. If I do they're mostly old fashioned singles. Maybe trying a bit of mass load (perhaps just 3-5 grams), then correcting VTF you get better tracking. BTW, how do you set up anti-skate? Did your deck come with the NA groove-less disc?
Regarding the leaving the motor plugged, they say you can do it, but I don't. I just unplug it every time I stop using the deck.
