I'd recommend option A simply on the fact that using the unmount option can potentially save card corruption. I've swapped out many cards, but without that option, I've had some show as corrupted when connected via usb set to mass storage. It can't hurt and can only benefit you in the long run to perform this extra step.
Will these methods work on my Motorola Droid Razr Maxx since I'm rooted with safestrap installed (and an "sdcard-ext" directory as well)? I have the stock 16 GB card in my Razr currently but wanna put my old 32 GB in if it's not too much hassle.

Those methods should work fine. The problem its that the sd-ext partition isn't going to show up on a fat32 system. But since you're rooted you probably have titanium backup or some other back up app and you should do a full back up of user apps and then partition your new card with sd-ext and a fat32. Try 4Ext from the market as a recovery image, its touch and it partitions and formats great.
