What can I expect from the registry awards.

Being new to the registries, I was wondering if anyone could enlighten me about the registry awards. If a person has a "best in catigory" award symbol next to their set, do they recieve a plaque or certificate from NGC too? Or is it just the little ribbon beside their set, that they get? Also, if there are any certificates or plaques, when could a person expect to recieve it? Another question. Every year upon renewal of the paid subscription, does a person get another 5 free submissions certificate as well? Lastly, Why is the PCGS so hard to understand and use. Is it for the intelectual ellite or something, and why do they not accept NGC graded coins?
