I too have been learning photoshop for the last one month. Recently our tutor taught us how to make a template in photoshop. But as far as working with pen tool is concern, it's very much difficult to draw images and use this tool independently. It's very much similar ot the shape tool in coral draw. After gone through your clarification i'll try it with much enthusiasm.

I was planning to design a theme soon thanks for sharing the post

I have the same thinking
