CONFUSED - I am a little confused over some comments our Home Teacher has made. He claims when we die, we will NOT be in the presents of our Father in Heaven due to the fact we will be too busy making other planets and populating them. He said that when we reach the celestial Kingdom we will in the presents of the son ONLY. But that is ok because the Father and the son are the same person.

JOEL - Actually I think your hometeacher is the one who is a little confused or perhaps just not explaining it well.
Speaking of those who inherit the Celestial Kingdom the scriptures say:

"These shall dwell in the presence of God and his Christ forever and ever." (D&C 76: 62)

We really don't know what the conditions will be like in the Celestial Kingdom, but as this scripture states, we do know that both Heavenly Father and Christ will be there.
Whether or not we will be "too busy" to be in the presence of God the Father, is pure speculation.
Speaking of those who will inherit the Terrestrial Kingdom, D&C 76 goes on to say:

"These are they who receive of the presence of the Son, but not of the fulness of the Father." (D&C 76: 77)

So it is these people in the Terrestrial kingdom who will have the presence of the Son only.
While it is true that the Son can represent the Father and stand in His place at times, they have always been two separate individuals.
