No, this isn't necessary.  The Macintosh will automatically start up from
a floppy disk ... so long as the floppy has a _working_ System Folder.

From page 215 of the Macintosh System Software User's Guide (the latest
version of it, which is 6.0):

	"Your computer uses an order of precedence in looking for
	a startup disk.  Searching in this order, it uses the first
	startup disk it finds:

	- internal 3.5-inch disk drive 1
	- internal or external 3.5-inch disk drive 2 (if there is one)
	- startup device set in the Control Panel of a Macintosh SE
	  or Macintosh II
	- internal hard disk or SCSI hard disk with device ID 0
	- devices connected to the SCSI port in decling device
	  priority number (from 6 to 0)"

So, Kuniaki (the original poster) should still power up his external hard
disk first.  Then, insert the floppy into the Mac Plus' internal drive,
and then turn it on.  If the floppy's system software is good, it'll boot
from the floppy.

Incidentally, I believe that "disk drive 1" is the lower drive on a
dual-floppy Mac SE and the right drive on a dual-floppy Mac II or IIx.
