BTW, this is a Duemilanove w/ ATMEGA168.
I'm not understanding your instructions for #2. I'm assuming I at least have to connect the serial ground to the Arduino ground, right? Are there other connections needed?
For the sake of others I want to make sure that this is clear.
as source of info...

|6||Data Set Ready||DSR|
|7||Request To Send||RTS|
|8||Clear To Send||CTS|
I think you are suggesting this mapping:
Serial 2 -> Arduino D1
Serial 3 -> Arduino D0
Serial 5 -> Arduino Gnd
1. Is that it?
2. Will that allow me to both program and use Serial Monitor in the IDE?
2a. If not, would using the ICSP header via Atmel STK500 be an option?
