Sort A Created Labels

I'm a novice at Excel and need some help. We have a local area Dollars for Scholars high school chapter auction coming up and I need to sort the information that has been entered into an Excel spreadsheet (there are several hundred contacts). I need this sorted to create labels to send out donation letters. Last year we used ACT, but the chapter board wants to use Excel so everyone can have the info at their fingertips (since everyone doesn't have ACT). The information was entered in column A like the following (in rows not columns):

Name
Address 1
Address 2
City, State
telephone #

Name
Address 1
Address 2
