So you're installing the firmware again, after replacing the internal card, right? If yes, remove the calibration app from utv210_root.tgz and add the new one (ut-tscal) so the new one is flashed. As it's a new installation, you don't need to clear cache as steev explained earlier. About the bigger card, you don't need to do anything, the extra space will be added to the /sdcard partition. You only have to change the partition values if you want a bigger "internal area" (normally it's 1.5GB and it's more than enough IMO, at least until we can find a fix for the slower boot with increasing number of installed apks).
