There are some things you can do to make this a better beer...
First, read all you can BEFORE you brew:
here's a good place to start

If you want to start a little further along the Homebrew path, read section 2,
Brewing Your First Extract and Specialty Grain Beer... that will give you some good tips on how to make this an even more wonderful American Amber Ale... however, what you have WILL make beer!!!
Look at the BJCP guidelines for Amber Ale for some info about this style...
http://www.bjcp.org/styles04/Category10.html#style10B
I'd suggest maybe another 1.5 oz of the Crystal hops as they are lower in AAUs... 1.5 oz for 60 minutes, 1 oz for 20 minutes and 1 oz for 2 minutes should bring you up around 32 IBUs (it depends on the AAU% of your batch of hops)... the 7 lbs. LME should give you around 1.050 OG and that would be a nice balanced beer IMO
Also, check out ProMash
http://www.promash.com/... this is a WONDERFUL program IMO and I use it for all my recipe formulation... use the free evaluation and see if you like it... there are other programs as well, so look around and chose the one you like best
Hope that helps, and Welcome to the wonderful world of Homebrewing!!!
