Airport for home entertainment (1st post)

Hi all, first post so take it easy on me! I've tried a quick search to find an answer to my query but with no success.

Its a simple one...

Just moved house and got a new iMac, with wireless broadband setup through SKY.

I'd like to play my iTunes music and listen to local BBC radio stations from my Mac and internet wirelessly around the house.

If I buy a Sonos S5 speaker and an Apple Airport (and plug them together), is that all the hardware I need to be able to do this???

Many thanks for your help,
Dom
