Moose,
Your questions to ask are basically correct except 1!
If you leave at 4 AM in the morning and return at 6 PM you stated that it was able to be deducted as a per diem day.
This is not considered a Per diem Day due to the fact that inorder to receive it you must be out 24 hours and in either a Motel, or in the Sleeper combination of 10 hours. His total time away is only 12 hours. and it is not a legal deduction the way you described it. If he was a paid employee and went to the office, factory, etc, he is not reimbursed for meals. The per diem is for Meal reimbursement only nothing else.
The other one is about the $5000 you paid to the IRS, If it is income taxes owed, (NO) it cannot be deducted (IRS Publication 334, chapter 8, Page 36 lower Right corner. ) If it is paid estimated tax, that is deducted on line 63, form 1040, Not on Sch C. as a business expense.
