Pardon if I seem stubborn, Kristin, but that's not really as "complete" an answer as I was hoping for. The topic of establishing your tank's cycle is very important. If we are not absolutely sure, then we must be sure before we proceed with more fish.
Do you know the tank has been through the cycle, or are you just assuming it has because your water parameters are checking out okay? I have a 46-gallon bowfront too, and I cycled with fish, so I can tell you from firsthand experience that your bioload may be sufficiently small that it could take a couple or three weeks before you have sufficient ammonia buildup to be detected, much less start the cycle. I have my doubts that you are ready for new fish, but if I am wrong, I will be the first to say so.
Can you list your water parameters from the LFS here?
Also, if you are making the commitment to keep fish, you really really need to invest in a comprehensive water test kit. Although it's great that the LFS will do complimentary tests for you in the beginning, you should not learn to rely on them. I promise it's an investment you'll thank yourself for down the road. You need a kit that tests pH and for the presence of ammonia, nitrite, and nitrate, at a bare minimum. Unfortunately, most comprehensive test kits do not include a nitrate test for some strange reason, so you might have to pick that particular one up separately.
Before you proceed with more fish, it is important that we know what state your tank is in cycle-wise. If you post your water parameters, we can tell you. It is very important to understand your water parameter readings, and what they say about what's happening in your aquarium.
pendragon!
Edit: Oops, first time through I didn't notice the part where you said you confirmed readings at home. You obviously have at least some testing material already.
