No (nor is it an oxymoron, which I think is more relevant); a paradigm is a defining pattern, and quite including a pattern of action. Its frequently used in a way which implicitly references a pattern of thought, but its not redundant to make that explicit.

Hmm, interesting. I've just checked the OED's definition, and it seems to mostly relate to thought - essentially, "paradigm" as "mental model".

However, the idea of an action paradigm is interesting - can you give an example of usage in that way?
