Pooks, two things: (1) the person (woman) at my LBS was sure that my bike was the right size for me, too, so they do not actually know everything, and (2) the Brooks saddle may not be able to go back as far as a regular saddle, and that might be causing you problems. That is exactly how I figured out that this bike was really, truly not fitting me; I put on a Brooks and kept climbing off the back of it trying to get a good pedal stroke.

You might try raising the seat a little. Even on an upright bike like a hybrid, that might get you back a bit.

Since my 7cm stem didn't arrive and I really need a rideable road bike for a class I'm taking tomorrow, I am going to get the only other option we found locally, which is a Ritchie adjustable stem. My husband thinks it will be too much and make my steering very squirrely, but I am buying it from REI so if it does not work out, I can return it after the 7cm arrives. I also got a set of cyclocross levers and we'll install those tonight (although my husband is really never going to stop calling them "chicken levers," not even if I kick him really hard).
