5.  When I configure the sdcard as external storage, it says I need to format it.
Only fat32 works for sdcard, if you have a different fs you'll need to format it. If it still says your sdcard is corrupted, you need to reboot into recovery and delete the .android_secure folder found in external sdcard.
