Using software serial is certainly an alternative. However I wouldn't use arduino pins 2 and 3 as that would preclude using them as user interrupt pins which can be a powerful and more important use for those two specific pins.

That's true.  Especially in this case where you're building it into the board.  Take a look at the other uses of the various pins and pick one that you'll never want to use for this particular device.  I use 2,3 on boards that I can change easily. 

Your mileage may vary.

For me, using pins 8 and 12 (PB0 and PB4) work out beautifully. The resulting PCB routes are cleaner and more direct than criss-crossing all the way over to the RX/TX pins :) Thanks for the suggestion!
