Ryno,
First, congratulations!. I believe God only blesses the very best couples in the world with multiples. I am sure your life will be touched in many wonderful ways.
Second, I can't speak from the experience of triplets, but I am the father of boy/girl twins. I can't even imagine having triplets. While the blessings far outweigh the sacrifice, you will find that your life is going to be tested to the maximum. Your wife should start meeting with members of a local Mothers of Multiples (MOM) chapter now. She will get a great deal of support there.
You job as a husband and father will seem overwhelming at times, but hers will be ten times more overwhelming. She will need as much support as she can possibly get.
Again, you have been blessed with a wonderful gift, but prepare yourself for the greatest change in your lifestyle you can ever imagine. You and your wife both have my prayers and may your future as a family be as wonderful of an experience as mine was . . . at least until my twins were in their teens and my wife and I divorced. That was the hardest thing I ever went through.
I don't know what your spiritual beliefs are, but stay close to God. He has blessed you with this experience and He will provide you with guidance.
Best wishes,
NCU
