Should a student focus more on securing a job or learning the language during the post-study work visa period in Ireland?

Focus primarily on securing a job during your post-study work visa period in Ireland. Since you have already studied in Ireland, your English language skills should be sufficient for most roles.

If you feel your communication skills need improvement - especially for interviews or workplace situations - work on language skills alongside your job search. Balancing both can help, but prioritizing employment will give you the best chance to transition to a long-term work permit and advance your career.
