-If it were me, I wouldn't break out all of the pins unless you need to.
-I'd also flip the solder points to be single side instead of thru-hole. Can then put it in a case and solder it without having to deal with both sides
-Make it square and/or panelize it. Round is the worst shape for per-inch pricing the way Oshpark does it.
Don't take any of those as complaints, these things are MFD.

1. The vias are on the pads to make it easier to fit stuff. I figured that they're all part of the same signal path anyway, so unless it starts messing with my soldering it's not a problem (I think).
I
hate the autorouter. It never gives me what I want...
2. It's meant to snap into the case, and mounting holes cost money.
Seriously though, I have made some with mounting holes and some without and I've found that if anything the ones that just snap in are easier to deal with albeit definitely more sketchy. The headers align it with the casing to some extent, or you can glue it in.
3. The only pin I may not need to break out is the 3.3v pin, as the 5v pin is suitable. But, I wanted a power supply pin available on SPI interface. Everything else is unfortunately necessary.
4. Hm I'm look into making squares, I might be able to get it a bit more compact that way too.
