I put this project on the back burner for a little while so I could try to learn more about electronics. I did learn a little. I make my living as an artist, so making things of all kinds holds my interest. Making my own PCBs is now on my gonna-try-that list. The small machines for which these PCBs are intended are nearly completed. I'm anxious to put them to work, as they will allow me to do things I can't right now. These PCBs are all that's left after I do some final sanding.
I have a double sided copper clad board on it's way in case I need to replace the two boards with burned traces. The first PCB I made works. Another has 4 repairs, and doesn't work, a third has 1 unrepaired trace, and doesn't work, and the last hasn't been tested yet. All are still assembled with components soldered in place.
I wish I knew someone close by who was good with these things. It's easier to learn directly from a person with whom a conversation in real time can be made. I'm wondering if I should desolder these two faulty boards to try to isolate the problem?
These are the directions I followed: http://www.dreamingrobots.com/ElectricEelWheel/BuildersGuideElectronics_v1200/

Thanks so much, you all.
There's so much here to digest, it's hard to know where to start. Maybe what would help most at this point is for someone to sort of take me step by step through the process of learning what's going on with these boards of mine.
I have a box of salvaged PCBs, mostly from several laser printers I deconstructed, from which I want to reclaim the components. There are many dozens of boards; large, and small. I can't afford a solder pot, have considered making one with a 3" cast iron skillet on a portable electrical burner, or using a heat gun; I'm not really sold on the solder suckers I've seen. That in mind, I could buy / make whatever to use to remove these components, but do I remove them all at once, or one at a time? I'd also be interested in hearing your recommendations for a desoldering tool. Thanks again.
PS: I appreciate this demo on repairing burned traces:
