I found pre-canned parts for the AVR, the MAX232, and the LM1881. Note that the AVR is labeled as an ATMega644P but it is the same size as the 324P which I intend to use. Even with 40 pins, space seems tight, so I think moving to the 40 pin model up from the 28 pin model is a wise move.
I doubt I will be able to find a precanned part for the LD-V1000 connector so I will probably have to *gulp* make that one from scratch. To quote Zed, "nothing is ever easy".
