Some packs do seem to improve after a few charges.

My older charger has been flashing up odd error messages for years but it still works and no lipos have exploded on me so I'd say nothing to worry about.

0.03mv is insignificant enough it shouldn't be an issue. In normal use even perfectly balanced cells will likely be that far apart under load anyway.

Set the LVC as high as you can but its not an issue when racing as in a typical race you'll only use about 1000-1500mAh. Its useful for practice, bashing or if you forgot to charge only!
BTW don't forget when you finish to disconnect the battery. LVC only stops the motor, but power is still drawn to the reciever and servo, so leaving the car on can still kill the lipo.
