Just change the settings under the WAL section of the config file. The
WAL files themselves will end up in the pg_xlog directory in pgdata, but
you can define the archive_command setting to archive the files off to
another directory.
Refer to the WAL section of the manual for details on what to set the
settings to.

How much hard-disk space you need is largely dependant on the size of
your database and the size and frequency of updates coming through.
