Wow That Black circle was such an important part of this image and Iam , your 1st example is the one i used , it was pritty simple and easy to understand , Though i think you forgot to mention something really important , i.e the shape created using the Elliptal tool needs to be rastisized for the "Stroke path" option to work .
The 2nd example is the one that i would love to try and when i do , i'll surely use your square brushes 
(Thanks for the brushes) , i never taught it could be done that way , so i'll certainly post it in the same thread later .
Div8 , Hmmmm you always have something out of the box , By the way someone deleted my file , so i'am going to recreate the whole PSD document and post it in a few mins . Also thank you for your time and patience and uploading the tutorial .
Iam below i have created the dotted circle , i got it after a few tries .
Ibclair , i see you have a eye for perfection but i am just trying to get all the effects and structure right , though a better approach might be to refine each section as you go , I am just trying to create something fuctional and pleasant enough . to make it speactacular though , we'll work on the refinement part in the end 
ty for your observation though.
