Breeding boosted horses is like breeding 2 horses of the next generation up. If you (fully - 5%) boost your foundation horses they are basically equivalent to 2nd generations. So your foals have a head start. They will officially be 2nd generation, but will have the abilities of a 3rd generation!

The best way to insure more intact foals is to use your pastures. Make sure the mares and stallions have similar papers regardless of what ACTUAL generation they are. If you are shooting for even pedigrees you will need to be a bit more careful of which paper levels you breed together.

There is no intact rate benefit to breeding boosted horses. If horses are boosted in quality, they may throw foals of better quality but the foals also have to be better to stay intact. So no benefit from the getting more intact point of view.
Personally I try not to boost too high, I will boost lined stallions so they are superior to sire, or boost mares to my minimum standards for that generation if she was some special colour, and I will often boost foundation stallions to exceptional level. But I personally don't boost foundations to paper 'A' say, I will use boosted stock occasionally but don't really hold them to a higher level than the rest of my stock, they just make it easier to meet my minimum requirements!
Pastures are definitely your friend for getting better intact rates
