A CPL and Instrument rating is required to have, before you can do the Flight Instructor Airplane checkride.
As said above, you can do them in any order you want to. Remember that for the PPL, IR, CPL and FOI writtens an endorsement is required from a CFI or AGI. There is not one required for the CFI written, or de CFII written.
I have to agree with B200Drvr, in that the CFI is the most difficult checkride around. I found it harder then any of my other FAA and JAA exams. Don't underestimate it, especially if you don't have any other experience teaching.
