Good points, but I'd urge paying off the mortgage before (4). Paying it off twenty years early saves a wad in the long run. And not having mortgage payments as a recurring monthly drain makes (4) easier.
Actually, you are wrong. Why pay off debt that is only costing you 6-odd percent a year (or less if you managed to refinance a few years ago) when you could invest that money and average 8-10 percent a year (or better). If you have enough money to pay off your mortgage, shove it all into the stock market. You'll come out ahead over the 30 years you're paying your mortgage.
