This is for a Canon system.
I am posting 5 options for Pocket Wizard use.
1. You only want to trigger a strobe remotely from your camera.
You need at least two pocket wizards (either 1 receiver/1
transmitter type Plus series, two Plus II, or two multimaxes) The
transmitter mounts on the hot shoe of your camera and the receiver
connects to your monolight or pack. You will probably need a 1/8
to 1/8 mini cord. to connect the receiver to your strobe. You can
use this one

2. You want to be able to remotely trigger your camera.
You will need buy at least the two pocket wizards above plus a
motor cord for your camera. The receiver is mounted on your hot
shoe (not required it can just hang from your camera) and the motor
cord runs from the PW into the remote socket on my canon (probably
similar on the Nikons). There are two types of these cords. One
has pre-triggering which is like depressing the shutter release
half-way

The transmitter is triggered from your hand.
3. You want to be able to remotely trigger your camera AND fire
strobes without a third pocket wizard.
Same as two above, but connect a standard Sync cable from your
strobe to the camera's sync socket
4. You want be able to trigger the camera remotely AND a strobe
without wires.
You will need either a second receiver from the Plus series or
either of the mult-max/plus II. So now you own THREE PW. You will
also need the motor cord and 1/8 to 1/8 miniphones listed
previously.
One receiver goes on the camera as listed in 2 with the motor cord
running from PW to camera. Another receiver is attached to your
strobe with the small sync cable. You keep the transmitter in your
hand and set them all to the same channel.
5. You already own a Sekonic lightmeter with the PW transmitter.
Then you could just buy two receivers and use the Sekonic to
trigger the camera and strobes as in example 4.
****************
I am currently using the regular PW Plus series receivers and own
both the regular motor cable and the radio shack mini phone cables
and have been very happy with the results. I use option 5 alot in
when doing portraits because then I am not tethered by the regular
canon remote.
I am sure others can debate the relative advantages to the Multimax
and Plus II systems, but if you are just starting out then the
regular plus kit from B&H would be fine. However, you are still
looking to spend between $375-600 depending on which option you
want to deploy.
My two cents
