Yeah. rd=diskXsY flag is for those with mbr scheme I think. No such thing as active partition in GPT, am I right?

"Default Partition" is just that: the default partition Chameleon will be set to boot. If it's not set, default will be the active partition. If youre on GPT scheme, the partition Chameleon is installed to will be default? So yes, in your case if you want Snow to boot by default you will need it.

So, boot-uuid flag is for GPT, rd=diskXsY is for MBR I think. Thats only for RC3 anyway. I still use both though.. no harm done.
