I'll add to Wayne's post, that unless you live next to Cd'O or Sheldon's shop or one of a handful of other shops in the US (many staffed by CR members), you will not get any answers to your questions at the LBS. Heck, LBS staff are rarely aware that current road rings come in "Campy" and "Shimano." At best they will know that road and MTB aren't usually the same.

First, don't be afraid to ask a "newbie" question like "will chain rings from a Chorus/Athena/whatever crank set fit a Super Record crank?". Answers to those types of questions (especially what-fits-what) are almost always available from the CR knowledge pool. Of course, it's generally best to ask before you make the purchase!

As you've learned, your Chorus crank takes 135 BCD chain rings and your Super Record crank needs 144. To make matters worse, your Dura Ace uses 130. Also, 144 is more limiting in chain ring choices than 130 or 135. They also may cost more and are harder to find. However, you also need to take the bottom bracket spindle (axel) into consideration. Depending on what BB you are using with the DA set, the SR will probably be okay. However the Chorus probably needs a different BB.

Second, ask yourself what it is you're trying to build. If you are trying for a period-correct, matching-parts bike, then go for it. But, if your bike is more for "function" or might be a "hot rod" classic, don't be afraid to mix and match components. Be aware, however, that there are lots of incompatibilities in the bike parts world. At the same time, there are things that are purported to be incompatible but really aren't. Confused yet? Post the question. You'll probably get the answer you need.
