Also I would have high PCTFREE to lessen number of records per block - if
you will have a lot of buffer busy waits. If you have enough memory - simply
increase size of KEEP pool to get enough space for needed number of CR
blocks. You will have to experiment with size of KEEP pool and
v$buffer_pool_statistics - purpose to eliminate physical reads.

Don't put it in a buffer keep because of the amount of
consistent gets the table could have. It seems to be a
high volatile table.
Maybe it is too late but you should look on the
initrans, freelist of the table. Also if the table has
foreign keys, talk with Development to leave the table
without them. I should consider to partition the
table....maybe a hash one.
