I am just talking about the audio part here , for video part , you'll have to use HDMI anyway !

ASTRO to your HT , basically you'll have to get Coax Cable http://cdn1.ioffer.com/img/item/112/615/162/AA7I.jpg for your audio !

PS3 to your HT , basically you'll have to get this http://www.tufts.edu/programs/mma/mrap/ana...ory/TOSLINK.jpg , a Toslink cable , link em up and you can have it working

If you got a nice amp you can basically connect all of these devices to your amp and just use one single HDMI output to your TV. But your HT does not take HDMI Inputs , it only takes audio input
