Answer

1, 2 and 3 are wrong. 4 is the only one that is correct.

Answer

Options 2 and 4 seem the most natural to this native English speaker from this particular area of the USA. Prepositions are so tricky. Your intention would be clear with any of those options. Have a good trip!

Answer

As a test, I searched for "busy ... packing my luggage", in quotation marks. I changed around in, about and with, and checked the number of results.

If you do this as well, you'll see that Paul's answer is perfectly correct: no preposition. The results that used "in" and "about" are written by non-native speakers. "Busy with" is extremely uncommon.
