I'd look into one of the third party books. I shoot Canon, so can't recommend a Nikon one in particular, but I liked the books David Busch wrote. I believe this one is the comparable one to the Canon books I bought.
Waiting to see your images! :) Read the manual completely. Don't skip anything, especially safety instructions and precautions. You're going to have to care a lot for it because we people start to love our camera. haha!
55-250mm standard lenses. Dual tube macro flash and external speedlit...
I am a Nikon shooter as well. Check out Thom Hogan, I have used his web site and books when I get a new body. Back when I bought my D200 he had a great chart for it on how to set the settings for different subjects. It made my life of switching between sports, portraits, etc. easy.
Here is his review of the 5100 - http://bythom.com/nikond5100review.htm and it has a link to his "Complete Guide" on the page.
