Retirement tax questions

Yes Taxable.  There are some exceptions like if you buy a home using your IRA you can avoid the 10% Early Withdrawal Penalty if you are under 59 1/2 but that doesn't apply to you since you are older.  When you turn 70 1/2 you can make a direct distribution to a charity from an IRA and avoid the tax.  

See IRS Publication 590B on Distributions
