Congrats on the new bike, I'm happy to hear you say how much you like it. I just wanted to add that I agree about taking your bike back to the shop to ask about the brake levers. A lot of times they can be shimmed to make it easier for you to reach from the hoods. This is a common problem for a lot of women who tend to have smaller hands.

Also, take your time with the pedals. I started with cages because I wanted to get used to the bike and the STI shifters before I had to worry about my feet. I'm very glad I did this. However I quickly got to the point where I was comfortable shifting and handling, and the cages were starting to frustrate me. That's when I knew it was time to go clipless. Clipless has a lot of advantages, but I think it's important to get the hang of everything else first so you enjoy riding. I think some people get pushed into going clipless too soon, then they end up hating to ride (when its not really riding they don't like, its the pedals). So it may take you a couple of days, or a couple of years, just do what feels right for you. (At the same time, don't be too afraid to try it, yes it's a little scary at first, but you'll quickly realize how wonderful clipless are and you'll never look back). Enjoy your new ride!
