System tablespace 1 gb

temp      "       3 gb
rbs        "      3 gb

Now keep rollback segments as big as possible and leave around 1.5 gb free in rbs tablespace.
you can increase your SGA upto 1/3rd of your ram. initially keep sort_area_size = 1m.
and later when your system is up check during peak working hours. sort(disk)/sort(memory) from v$sysstat.
If it comes more than 5% than increase your sort area size.
