Well it looks as if you are getting answers on all the forums you posted this on so we might as well post here. ;)

JMO but if you already know or can easily find out from the local county extension what the basic structure of and mineral content of your native soil is then all you would need is the basic test IMO - pH, N-P-K, and organic content.

But if you don't know or can't get that info for some reason or if you have trucked in soil or have new construction zone soil or if the garden area has been abused in some fashion in the past (like it used to be a garage floor or dump area etc.) then go for the advanced analysis this one time so you will have all the details on just what you have to work with.
