RE: What would you do with 8 disks?

It depends on your specific requirements - I'd start with calculating your storage, IOPS and MBPS requirements and then configure the disk to best meet those requirements.
If you need the storage capacity, go with RAID 5 If you're doing mostly reads, and can tolerate severe slowness in the event of a failed disk, go with RAID 5 If you're doing a lot of PHYSICAL writes, or can't tolerate slowness with a failed disk, go with RAID10
Don't worry about splitting out redo logs unless you need very high performance DML and you have very frequent commits - and then you might want to consider using an SSD.
