You will not need a crank puller for the Ultegra crank arms. Here is Shimano's diagram of your setup; http://bike.shimano.com/product_imag...FC_6503_EV.pdf
All you need to do is back the crank arm fixing bolt out with the crank arm cap in place and it acts as it's own crank puller. As long as you use Ultegra crank arms you will not have to replace the bottom bracket.
Great link and info! Now, do I have the confidence to start turning the wrench? That is the real question!
