So v4.0 of PCB (just finished; after testing confirms they are good, I'll release to the wild) has the ISP header for flashing a bootloader to the Atmega. This is also because the new pcb design went 100% SMD :) So removing the atmega is no longer an easy option and we need a way to burn bootloaders because atmegas with bootloaders preprogrammed are expensive for no reason.

Having said that, you'll need 2 arduinos if you wanna burn the bootloader to a blank 328 chip; one as the ISP (in system programmer) and one as the chip to be burned. It's easier to buy a bootloader burner like Karlis said, but if you're only doing 1 or 2 or 3, it's prob not worth it. You can google how to do it on a breadboard if you're only doing that many. It's just a few wires.

I also have a template cut out of metal that I use to cut the hole for the cdc connector. The car's connector mates up to it fine with the connector protruding through the case; no need to cut the hole super large for the locking tabs; they lock fine.
