I already have my PPL, will probably do about 50hours hour building or so, probably florida-vegas-florida, then ATPL.
Since you're going the full hog, best get to grips with the terminology!
Admittedly it is all a bit confusing at first but the Air Law exam will clarify eveything...
You'll need 1500 hrs for an ATPL - I think you mean the CPL-IR, which when combined with the ATPL theory requirement (ie the 14 exams) can be termed 'Frozen ATPL' though there is no such licence, so you will just have a blue CPL initially.
