3) The $70K account is so small it is not an issue for estate tax planning. The maximum allowed in total (lifetime) remains $1M. Your father must file the gift form with the IRS on his next tax return if he gives you the full $70K, for the reason below.
Actually the lifetime exclusion is currently $5.12 million for 2012. The father would have to file a gift tax return which is separate (not a part of) from his normal income tax return.
The $13K/annual gift tax exclusion can be aggregated for up to five years of giving; e.g., your father can donate up to $65K to you, in any one year, WITHOUT having to file a gift tax return with his usual IRS return.
This is wrong. There are some circumstances in which you can allocate the gifts to 5 separate years and thereby use the $13K annual exclusion for each of the years (most commonly is gifts to qualified tuition programs like 529 accounts), but you still have to file the gift tax return to make the election. This is not one of those circumstances.
