Might I suggest switching to a PIC 16F628? It has almost the same pinout as the 16F84 and can be programmed with the same hardware, but has a hardware USART, D/A conversion, more I/O lines, and a lot more program memory. For some reason, it's also cheaper.

I rather suspect a 16F84 will choke on something that complex. You won't be able to use interrupts to deal with the wheel encoders, because the 16F84 only has one external interrupt line. Are you using digital gyros, or analog ones with a pile of serial ADCs?
