ShouldI get rid of all items under my $PGDATA and leave the empty before doing the following?

Just to be sure the target is the standby server, correct?
If so you do not want this:
-h <my target hostname>
-h is for the server you are taking the backup of, or to put it another way the flow is from -h to -D.
If you are running pg_basebackup on the same machine as the primary then:
pg_basebackup -D <my target host directory> -P -U replication --xlog-method=stream
This assumes there is only one instance of Postgres running on that machine and it is running on port 5432. If not then
youwill need to specify -p <correct_port>
pg_basebackup is a client program, so like other such programs you have to tell it what database(cluster) to connect to
usingthe normal switches, see below. Actually pg_basebackup does not connect to a specific database but to the database
cluster,so any database name you supply will be ignored.
