is right. Your only output is SPDIF.
1. 75 Ohm male to male RCA coaxial cable (goes in the red plug to the right of the HDMI inputs)
2. SPDIF to analog audio adapter box
3. Whatever cable your adapter box and amplifier takes:
A. stereo male RCA to male RCA
B. male RCA to 3.5 mm adapter cable
C. 3.5 mm on both ends audio extension cable
As for the other plugs, the crap on the right are input only. Top to bottom: composite video-in (R,L,Video). Takes input from SD surveillance camera, VHS machine, old camcorders etc. Component HD video-in (R,G,B/Y,Pb,Pr), that's usually 1080i signal.
Damn what a shit TV though. Doesn't even have a headphone plug. The plug next to the VGA connector is line-in.
