You've done a great job of saving!
Your emergency fund is a bit rich. If you lost your job, how long do you think it would take to find a new one? If you suspect a short turnaround, you only need a few months of expenses and they should be fairly liquid, so your savings account is good.
You mention your stock/bond allocation, which seems high in bonds, but everyone has a different comfort level with this. Do you have individual stocks? Most here would recommend low cost total market index funds instead.
How are your retirement accounts invested? These should also be in low expense ratio index funds.
Paying off the mortgage is controversial here. We paid ours off and don't regret it for a second. Others will say to keep the mortgage and invest the money. Not having a payment is really nice if your income drops.
Even if you do pay down your mortgage, you'll get the money back when you sell your house, so I wouldn't worry on that end. Even if your house sells for less than you bought it for, the amount remaining on your mortgage doesn't change the sale price.
