tuning our database by increasing shared buffer

Hello,
We will be consolidating from 4 databases to 2 and want to make sure that
these parameters are the only ones that need changing.   Please advise.

Current                                Future
=====                                =====
Max_connection = 50                    125
Shared_buffers = 16MB                    48MB

My concern is that max_locks_per_transaction and max_prepared_transaction are
still set as default??

Shouldn't we increase the max_locks_per_transaction from 64 to 100 or 128
since we have more than doubled the # of connections?

max_prepared_transaction is set at default of 5 which is says if we use it to
set it to max_connection.

Or leaving those 2 max parameters as default would be ok?
