If the axle is off center, you likely messed up the threads on the drive side. I'd recommend taking it to a shop/coop and getting the threads chased.
When installing cartridge BBs, install the NDS cup a few threads (or a lot, just as long as it doesn't stop the bb from going all of the way in), then put the DS in, making sure the spindle goes through the hole in the NDS. Tighten the DS down all of the way, then tighten the NDS.
