Hi there,
After your PPL, you will to build your hours up to a minimum of 150, with at least 100 hours PIC (If I remember correctly), in order to begin CPL training.
However, before CPL training, you will need to pass 14 ATPL Theory exams.
You can do your ME course at anytime once you have gained a 70 hours P1, so this could be before or after gaining a CPL.
The CPL itself can be done on a Single-engined aircraft. Usually something like a C152 or PA28, then on to a complex type such as an Arrow or Comanche.
The IR is usually done after gaining a CPL, however it can be added to a PPL, in which case you must do the relevant ATPL exams and undertake a minimum of 50 hours of instruction.
If adding an IR to a CPL, you will already have passed the relevant exams and will need to undertake a minimum of 45 hours instruction.
As you wish to gain an fATPL, you will need to do a ME/IR.
I hope this helps.
