You forgot C8 that goes from pin 1, to pin 5.
Next time, it would be a good idea to keep the parts on the PCB labelled the same number(s) as on the circuit.

The traces thazt must carry up to 1.5A should be wider.
Here it is the revised circuit as per your input !
Don't you want to put your (-) side of C4 and C5 to ground right on your board? If so, get them connected to pin #4 on your chip somehow.
Looks like you may have autorouted your board. I like to Use PCBWizard and just go in and design my own. Seems like the first thing you do after autorouting is DIAGNOSTICS. By doing your own design, you know where things go and why. This circuit could probably be done on a 2x2" board. Although having a bigger board does allow room for later adjusments.
Your layout is poor, there are 0v line running allover the place.
You need to consider how to simplify the tracks and also consider the physical size of the components, not just the electrical schematic. You have some electrolytic capacitors with a 0.1" wire spacing, are you sure that is correct.
Have a look at my layout, it is a bit rough but may give you some ideas.
You can make the 0v and +Vs tracks a lot wider, this lowers the impedance and helps to make a stable amplifier.
I have streached the cole spcing on some of your decoupling capacitors, this may or may not be appropriate, depends on what you are physically using.
