Okay, my apologies for the lack of a prompt response, I've been rather busy lately.
Anyway, I looked into the 'Startup Disk' option on OSX, and the external USB drive I'm using never came up. But rEFIt recognizes the drive and allows me to choose it when I start up my laptop, so that's never been an issue. After all, I did have 11.04 running and able to boot with no problem before.
I've tried a few times to install 11.10 without making an EFI boot partition, to no avail. Every time I've tried to install, boot partition or no, I've always chosen /dev/sdb as my grub install destination. That said, you can probably get the full story from the result of the boot info script that I'll be posting below.
Finally, as to the partition table type that /dev/sdb is using, I don't know where to look for that, sorry. If you could kindly point me in the right direction, I'd be happy to tell you.
All that out there, here are the results from the boot info script:
