For both performance and availability reasons I would keep tend the setup of different luns for different part of the database , data, redo, archive, duplex, unless there are small database and/or only crash recovery is required.. You can create different Volume groups for each set of disks.. Definitely also a different VG for OS data.
It may be beneficial to spread the date over several LUNS in the data VG, with or without a small stripe, that depends on your workload and underlying SAN storage, to overcome bottlenecks due to the sequential nature of SAN connectivity (Fibre Channel, iSCSI). An alternative to the latter may be to enlarge the queuing depth, it all depends. The other Oracle VG's require sequential access, where a single disk (two lun paths) will probably suffice..

If you don't use ASM, you would need to determine if you want to use raw or cooked logical volumes within the VG's.
You need to set multipathing, and then there is the backup and recovery method you need to choose, etc..
