Could it be the 14-42 is sharper than you expected?

If you stop them down a little and look in the central part of the image most kit lenses are very sharp these days. I think the softest kit lens I have owned in the digital age was the 18-55 that came with the NEX-5N I owned and when stopped down to f8 in the middle of it's zoom range even it was sharp enough to create moire. The advantage of premium lenses are things like better performance wide open, sharper corners, faster aperture, more contrast, less CA, better build quality, less flare, etc.

If you think there is something wrong with your 45mm I would send it back to Olympus if it is under warranty.  Sometimes lenses will come with a decentered element or some other defect.  But there is nothing to calibrate.  Since m43 cameras use contrast detection for autofocus they do not have the front or back focus issues SLR lenses sometimes have.
