J,
Your spot on - PPL, ATPL theory, CPL and then Instructor rating. You could always do the CPL exams instead of ATPL but its up to you. IMC would be a great advantage rather than a full IR(depends what you want to teach at the end of the day i suppose). Just remember though, if you do ATPL's then you have 36 months from date of last pass, should you wish to add a full IR. If you dont get it within that period of time then you lose your ATPL exam privilages. If you fancied flying airline wise at a later stage then you'll need to consider those points. Re the job side of things, im sure you'll get yourself an FI job somewhere. If you were to teach CPL, multi or IR etc then you'd probably be looking a better salary too. All the best for the weekend!
