Hi I will try to answer you questions :
The size of redo log files is depend on the transaction activity, you have to monitor the Checkpoint activity and Log Switch activity, the ideal time for Log file switching can be minimum 15 minutes per Group, the information you can get from v$loghist. OFA standard is minimum 2 Groups per Database, you can define 3 Groups is OK, and each group s minimum 2 members or 3 members is OK. Hope this can help you....
