It all looks good from what I can make out in the pics. For the biasing of the fuzz, I think it says aim for about 4.5v (you'll need a digital multimeter if you haven't already got one). There is actually a way of working out the correct bias, but somewhere in the region of 4-6v will probably be in the right area. Saying that, there's nothing at all stopping you just putting it where you think it sounds best.
As for the clean boost mode, without looking at the circuit, I don't know what it's doing. It the crackle when turning one of the knobs or just there all the time? Otherwise, the forum on BYOC is your friend. All the questions about the kits will have been asked before on there.
