Since you are over the age of 59-1/2, this would just be a normal distribution for you with no penalties assessed. The amount you withdraw would simply be added to any other income you have for the year, and it is your total income that determines the tax bracket which you would fall in.
If you could tell me how much other income you think you would have for 2010, how much you plan to take from your 401k and if you file as single or married, I could give you a better idea of the percent you would pay on tax for this withdrawal.
