no worries, there are certain elements that are very generic and can be used by any designer, stuff like shadows and reflections or shiny effects.
the other thing thats fine to recommend is text. Unless a designer does something unique to customize his text anyone can use that typeface and its fine to recommend it to other designers. It's a similar story with colour's (especially if you mentioned them in the original brief.)
regarding info, take a read of this post:
