Got my 7 segment LED and shift register in the mail today. Wired it up and it pretty much worked the way I expected. I had to change MSBFIRST to LSBFirst, I had a feeling I had it backwards. If I had soldered the pins in the other order, that would have worked as well. Also, the 7 segment LED module I got is freakin TINY, I wondered what they meant by .28" in the description.. I think that meant each segment is just over a quarter inch long.. heh..
I also had my numbers off a bit, I needed to subtract 1 from currentMode to get the correct number to display from my array (starts at 0, not 1), and one other minor change to keep the LED from displaying 6 when I'm in mode 1.. 
I'm looking forward to Christmas being over so I can move on to my next projects..
