Physical Layout of disk to use Oracle

I am using Oracle 9.2.0.1 on IBM AIX 5.1L box. My box has 8 different hard disk hdisk0-hdisk7.

hdisk0 + hdisk1 are mirrored and house System ROOT BOS. That leaves me to 6 hard disk hdisk2-hdisk7. hdisk0 and hdisk1 both are 18GB each
hdisk2-hdisk7 are each 36GB

I was wondering what would be the best way to utilize these disk taking into consideration following points:
1) Contention Problems i.e.: 2 different process using the same disk and one

   has to wait.
2) Speed - without having any process having to wait a longer.

I have read Kevin Loneys' ORACLE DBA Handbook and read a chapter on Physical Database Layouts. Here is what I get....correct me if I am wrong.

hdisk2 --> Oracle Appplication Software
hdisk3 --> SYSTEM Tablespaces(for all instances) + Control File 1
hdisk4 --> ROLLBACK Tablespace + Redo Log files + Control File 2
hdisk5 --> DATA Tablespace + Control File 3
hdisk6 --> INDEX Tablespace + TEMP Tablespace
hdisk7 --> ARCHIVE Redo Log destination disk.

Can anyone point out if there would be any issues in the above Layout. Please feel free to be as critical as possible....after all I learn from my mistakes only.
