Spils,
Basically, yes - as far as ground-school is concerned, you do an approved CPL course, then sit the exams.
There are two areas of confusion. First of all, there are only a very small number of schools who offer the course. This is because it isn't in very high demand, because most people prefer to do the ATPL exams.
The second point is that in most cases, many people (including me) would recommend doing an ATPL course anyway. The ATPL course entitles you start the flight training for both the CPL and the IR. You don't have to do the IR of course, but you have 3 years in which to do it if you change your mind and decide it might be useful after all. On the other hand, if you do the CPL exams, you can not start an IR course without doing the IR exams - and there's a lot of overlap between the two, and so potential for lots of wasted time, effort and money. So if there's even the vaguest chance that you might want in Instrument Rating, then do the ATPL exams instead.
