HELP! Shimano Dura Ace shifter question

Firstly, I am a Dura Ace newbie.. Okay, so I have Shimano 7700 RD/FD and 7900 shift levers for the down tube (they look intimidating to install). Dummy me bought the pair of shifters with flat boss washers instead of radius-ed ones.

<I also have a pair of bar ends that came with my Brewsmith Dura Ace package, but not sure whether I want to go bar-ends.>

My question is that there are ebay radius-ed boss washers that state Shimano 7800, and SL-6208...Will these work with them? Is the 7900 proprietary? Also will the 7900s work well enough with the 7700 derailleurs?

No matter what, I seem to be going in a direction where I will have extra parts due to my indecision...
