Pinterest is a lush! 
P.I.M.P basically tells you the backend stuff - the things Pinterest attaches to your pins without you knowing about it. It is a bit nerdy! Have found the SEO stuff most helpful. Actually, I am a bit addicted to JL courses - there is ALWAYS something in there I can use! Some can be quite 'slim' but they are cheap, and like I said there is always a nugget in there!
My current geekery over Pinterest is making video pins and sending them viral 
Also, re the anon thing, just change over your profile photos as a starter, update your about page. You can always transition. Plus real photos do better on Pinterest as they look like a proper pinner account rather than a business account.
