Hi Thunderchild,
I see most of your dilemma is caused by not having a proper PCB-layout for the amplifier.
Here is a suggestion for a quick PCB to make. Use the layout I designed very close to the manufacturer's design (without mixing up OUT A and OUT B, and not connecting unconnected pins of the TDA2009 (pins 7 and 11 are NC, but connected to pin 9 on the layout))
Print the layout normally and tape it to a copper clad. Then poke holes through the paper into the copper surface. Use an EDDING400 (800 for finer traces) and connect the "holes" according to the layout.
Etch and drill the PCB and you'll be finished in no time with a functioning amplifier.
