Those are awesome amendments! The only critique I have is the one about the fed paying its employees in gold only—how do you deal with the military, which, in war may number in the millions, and where would you find that amount of gold in a legitimate war, where, say the United States is attacked bodily and some states are invested by the enemy?
Part of my rationale for that is to keep the number of federal employees down; also the requirement that all payments to the States be gold should restrict the federal-payout game that they seem to be playing (i.e. by forbidding easy [eg electronic, or paper] transfer of assets the Federal government would be more inclined to not spend).
