Brewtoo,
That board looks like most of the ones I've worked on. I would be sure to touch up the solder points that you think look suspect.
The transistors are supposed to dissipate a maximum of 25W at full power, however these guys are operating at maybe 5-8% of maximum so I doubt they dissipate too much heat.
Yes the varnish remover easily removes the coating. I only apply it to the rear of the board when I do work on these as there no real need to remove it from the other side. The capacitors, once de-soldered, come out with minimal effort of the pliers.
Hope this helps! If you've got any other questions post up!
