Importing address info from a large spreadsheet and then creating address field -Step by Step?

Thank you Evan.  I did a small test on this and was able to get the info in a table, along with some other columns of data.  I only used about 750 records for this test, not the full  6000 addresses.  To your question, this was  an import of all new records.  

I'll have to do a few more trials to see if I really "got it down" with this procedure.  One other thing...I now notice that when I click on a record, the only info that comes up on the form is the map.....not any of the other fields.  Did I do something wrong when I imported the data this time?  Thank you very much for your help!  Mark
