Starting from scratch.

Hey all
I recently picked up x2 rear speakers and a centre speaker from a mate, I know very little about speakers or how to set them up.
So I am taking on board all advice

Centre speaker sepcifications:
Power handling: 140 Watt.
Frequency response 65Hz-22Khz.
Sensitivity(+/-3DB): 88db
Nominal impedance: 4 Ohm
Driver complement: 2 way, 3 driver
Woofer: Two 4" (100mm) midwoofer PPC.
Tweeter: 1x3/4" silk SCOS dome
Crossover frequency: 2700Hz
Dimensions(HxWxD): 48x17x14.5 Cm
Weight: 3.7 Kg

Rear speaker Specifications: (x2)
Power handling: 140 Watt.
Frequency response 65Hz-22Khz.
Sensitivity(+/-3DB): 89db
Nominal impedance: 4 Ohm
Driver complement: 2 way, 2 driver
Woofer: One 4" (100mm) midwoofer PPC.
Tweeter: 1x3/4" silk SCOS dome
Crossover frequency: 3500Hz
Dimensions(HxWxD): 14.5x17x24 Cm
Weight: 2 Kg

On the back there is just an input plug +/- thing..

So my question really is (and I am sorry it's so broad) is what exactly will I need in order to get these things going? some sort of receiver and speaker cables? I really don't know what I'm doing.. I just wanted some surround sound for my new plasma.

Any help would be much appreciated. Thanks again.

P.s. Are these speakers any good? I payed $300 (AU) for the lot. thats $283.52 (US)

EDIT: My TV has a digital (optical) audio output. So yeah, anymore information I can provide I will, I know my knowledge is limited but even if someone can throw me a link to some sort of beginners guide to setting up? I have to start somewhere.. everyone does
