Can somebody explain what these mean and how to interpret them:

W$SD%
AGG
AGG%

Also, I am losing quite a bit from the blinds is this a major issue and when should it be addressed? Got sick of poker a while back took a break now i am looking to grind through the micros, any tips from guys on this site that have successfully done this themselves will be much appreciated.
