Hans has contributed three chapters, including one on QRSS and one on the multimode transmitter shield, to the new ARRL book 'Hamradio for Arduino and Picaxe'. It's well worth a look, it would probably answer your questions.
If I've read it correctly, switches 1 and 2 give a value from 0 to 3 to select modes None/QRSS/FSKCW/DFCW, similarly switches 3 and 4 give speeds of 12WPM/QRSS3/QRSS6/QRSS10.
Loading Arduino sketches into ATtiny chips is covered here:
I think you will need an ATtiny44 or ATtiny84. The 8-pin ATtiny45/85 types don't have enough pins for this application.
Hope this helps.

Hi Hans and all,
I have a couple of questions about the arduino shield.
1: If I run the UNO battery power can I connect it to GND and Vin (as recommend by the arduino website) through your QRSS shield?
2: I have looked through the sketch to find out which DIP switch does what but due to my limited knowledge I cant make head or tail of it, can you tell me the various switch positions / modes? at the moment I have only switch 1 in the on position this seems to be QRSS 3.
3: I think it must be possible to upload the sketch to a ATtiny chip or similar (sorry lack of knowledge again) and breadboard the QRSS shield with the chip, what sort of chip would I need ?
