Hi Meatbomb,
Hour-building
Night Qualification
CPL
MEP
IR
is the usual order and the order in which I did it.
The hour-building is the best bit of training you'll ever do. Enjoy it. You can do the Night Qualification at the same time.
To start the CPL you need 100 hours PiC as part of a minimum of 150 hours total time, plus a 300nm cross-country including two stops and a Night Qualification. You also need to have completed the CPL theory exams. As most people want an ATPL rather than be restricted in job prospects by having only a CPL and having to occupy the RHS for the rest of their career, in reality you need to have completed all 14 ATPL exams before you are allowed to start the CPL.
To start the MEP rating you only need 70 hours PiC, so you will easily qualify by the time you start it because of the CPL requirements.
To start the IR you simply need 50 hours cross-country time, so by the time you've done your hour-building and CPL you'll qualify.
You apply for the CPL/ME/IR licence issue once you've passed your IR Skills Test.
Looks like you have the other info you wanted from the previous posts.
Enjoy.
