Other than that, the only thing you'll need to do is adjust the B-screw on the rear of the derailleur, and perhaps make some very fine adjustments to the limit screws. Most of the time, you won't need to touch the limit screws, but it's always best to start from scratch and set up the derailleur as if it's brand new. Also, you may want to add a couple links of chain, or just use a new one and cut it to the proper length.
If you need any help with all of this, a shop will do it reasonably cheaply, or you can visit the %26quot;repair help%26quot; section at http://www.parktool.com for great instructions and photos on how to do everything correctly.
If your girlfriend really kicks ***, you might still get embarrassed, but by changing to the new cassette you'll be gaining 2 extra low gears. If that helps your legs feel fresh after the climbs, then maybe you can keep up with her. LOL :o)
Good luck! :o)Will I need to make adjustments to the derailer when changing my road bike cassette to a larger one?Thanks, I was just going to ask this question.

Will I need to make adjustments to the derailer when changing my road bike cassette to a larger one?I just did pretty much the same thing on my Shimano setup. SWEET!!!Especially makes a difference on longer steeper rides. Everyone has some limit for their number of high effort standing climbs. With the 34/27 there are few that I have to stand and strain. That doesn't mean that stronger riders won't still be faster...
