I can't comment on the angle of the shocks being too much or too little, but this definitely sounds like you need to install the bar before shopping for shocks. Everyone's spring/ride height and lower shock mount combination is going to make a big difference in what length shock you select.

For mounting the bar, does the kit come with shoulder bolts that will keep you from squishing the frame rail when you torque it down? If not, I would suggest getting some and drilling your hole sizes appropriately. See Todd's (Vegas69) Payback thread for the section about mounting his swaybar for more detail.
