The limits are set to increase to $17,500 and $23,000, respectively, in 2013. You can continue putting money into a 401k plan as long as you are employed and have access to a plan.

When you reach age 70 1/2, you can no longer contribute to a traditional IRA, and you have to start making required withdrawals regardless of whether you are employed.
A Roth IRA is a type of private retirement account that -- while funded with after-tax income -- offers tax-free withdrawals. Roth IRAs have the same contribution limits as traditional IRAs, but you can continue putting money into a Roth IRA after age 70 1/2 as long as you have earned income, and you don't have to make required withdrawals.
