Hi there,
I would do your CPL first. I believe that you may have to have the CPL before you can do the IR anyway.
What are you looking to go in to? If your not one of these types who lives in the clouds when it comes to jobs etc, ie think your going to get on a shiny jet straight away, I would recoment the FI rating too. This would enable you to instruct and build up some suitable hours and experience.
If you need any more help feel free to PM
Hope this helps
