Probably a bit more to do than that unless you are extremely lucky.
You will have obviously got a new wheel that is compatible to take your existing cassette (Shimano or Campag)??
The new wheel will very likely need to be centered in the frame by adjusting the axle (slacken off the cones, move axle then retighten cones etc). When the new wheel is in you will be able to see if the derailleur is in line with the sprockets on the cassette, if it is then no adjustment necessary. If the wheel is just about centered and only a minor change required then fiddling with the derailleur barrel adjusters should do it.
You will also probably need to adjust the brake pads to go nicely on the new rim.
Then you can report back on the difference between the two wheelsets - I am very interested to hear what you find. Both wheelsets are currently on my shortlist...
