Well, I got a little closer messing with it last night...
First off -- this has all been with the battery removed. I was like "Oh? I can test this without spending battery at all? Yes please." :D
Now... what I got working was: I could receive data in the puck FROM the terminal.
I could not, however, get output from the puck to show up on the terminal. At all.
I assumed maybe I had a bad soldering job or something, but when I flipped the TX/RX pin connections and in the .setup() call... I could receive terminal input!
So... both of the connections seem solid.
Then I noticed on the FT232R, it's got TX and RX lights that fire up when data transmits over the respective channel.
Nothing I did could get the lights to blink when sending output to the console. Serial1.print(), Serial1.println()... none of it seemed to trigger actual outgoing data.
I believe I tested swaping the TX/RX pins as well.
Tonight I'll grab a different FT232R and do some more testing.

Well, try this
rx (D29) on Puck get's connected to tx on FT232R
tx (D28)on Puck get's connected to rc on FT232R
3V on Puck to 3V3 on FT232R
GND to GND
Hint: remove the battery :) so you can connect 3V3 to boot
Hope this helps and you get the serial working.
