Help please

System: Yamaha 5960 [NO HDMI] and Sony 50A10 [720P, one HDMI in and 1 optical out], Comcast HD-DVR, AVR to be upgraded in summer, TV later [I hope]. Speakers are DT PM1000/PC2000/BP-2X's & SVS PC 20-39+. So it is important that I get the best surround out I can.
1. Will the 390 output my BD to this TV thru component outs?
2. Will I here DTS-HD/MA thru the analog outs?
Another option is to buy a HDMI switcher [monoprice] connect both HDDVR & 390 via HDMI to TV. This should work fine, yes? If I go this way, would it be better to use the analog outs from the 390 or optical out from the TV to the AVR, which would give me best sound?
