The best advice I can offer you is to ask the pertinent questions from your Recruiting Centre when you actually enroll. Specifically, you must get a clear answer on whether you will be moved under the CFIRP or not. If you are being moved under the CFIRP, then read the CFIRP Directive here:

If you are not being moved under the CFIRP, then you should read the Compensation and Benefits Instructions here:

All of this may be a bit overwhelming, so if you have any things you want clarified, feel free to PM me with specific questions.
The most important thing to remember, is that the goal of relocation is to ensure that you are no better or worse off than you started. You should not be out of pocket, but at the same time, don't expect to make a profit either. Also remember that at least initially (while you are training), your postings may be "restricted" or "prohibited." This will affect whether your family will be moved with you or not. Unfortunately, only the Management Authority can decide what type of posting you will get. Your best conduit for that information, again, is the Recruiting Centre. At the end of the day, it will get sorted and be especially aware, that you don't necessarily have to do everything at once. If you want to proceed on course and have your family follow later when it is more convenient, that can be arranged.
That's a good piece of advice for everyone to be aware of. The day that a member has to report for his/her new job is not the same day that his Dependents, Household Goods and Effects have to be in place. There are provisions to allow members to report on time and move everything else at a leisurely, logical and convenient pace.
Bottom line: Don't panic - it's all going to happen.
