There are several potential causes of your tree's decline.  From the photos, it is difficult to tell with certainty which condition is causing the problems.  Winter injury, spruce needle rust, or spittlebugs may the culprit.  For detailed information about potential causes, including photos, see

To be certain of the cause, bring or send a sample to the U of Mn Plant Disease Clinic.  See http://www.pdc.umn.edu for details.
