Good work, Glad to hear it's working again.
Re speaker, Either way is fine, it only matters when you have more than ONE speaker THEN you have to make sure the polarity is IN Phase.
When more than one speaker the sound still works and no damage is done while out of phase but you tend to notice a loss of Bass.
When I met my wife years ago she had a stereo unit and she said her friend had the exact same unit but it had much better bass so I checked and sure enough the speakers were wired out of phase,, swapped the wires on ONLY One and bingo she then heard the Bass that was missing.
Yes adding a slip on heat sink can't hurt.
