I like how when it stops you can hear it echo.

Yeah, I thought that was cool too. Kinda gives you an idea of how loud it is, echoing off the neighbors house across the street.

Have you tried running it without a breakout point?

No, I haven't tried. As Dan mentioned, this is specifically advised against in the book. Too bad, I really like the look of an arc randomly floating around the toroid. I actually own one of your mini coils that doesn't use a breakout point and people love the little guy too.

Ah, yes, I remember being momentarily confused by this too. Fig 2-8 does appear to show the secondary wire going through the current transformers. This may be a relic from when Dan was using secondary feedback, I don't know. Anyway, it is primary feedback and as such, the primary lead goes through the CTs.

Is c32 needed? should I follow the schematic or the board design?

I have to admit, although I know enough to be able to follow schematics, I do not understand enough about electronics to know what c32 is supposed to do or what would happen (if anything) if I'd included it. Since it was not on the actual board, I left it out and did not actually notice it until later. Seems to work fine without it, maybe someone else can elaborate on its function?

Wire, are there any other obvious errors you found that you can remember? I just received my Digikey shipment today, so i'm sure i will run into some issues.

No other errors that I can remember, but some of the digikey part numbers had changed. I was able to find the parts easy enough by just searching for the part name. The 220V TVSs were one of them. Since you've already rec'd your order, I assume you were able to figure this out too.
