The ATPL exams are fine for a CPL - only thing to look out for is that you have to get your IR within three years or the exam credits expire and you'll have to go through the whole business again.
A fATPL is a CPL/IR with ATPL exam passes - it is frozen until you get the required 1500 hours (with assorted caveats, e.g. 500 multi-crew) for the issue of a full ATPL.
