Yes.as long as you do not contribute more than your annual limit.
You can contribute to both a 401K and an IRA at the same time (same year).
You can contribute to a Roth IRA after age 70.5 as long as you have earned income, but you cannot contribute to a traditional IRA after that age. For a 401(k) plan, it depends on the rules of the specific plan, but typically you can continue to contribute to it past age 70.5 as long as you are still working and the plan allows for it.

Yes, but combined contribution limits apply. For 2008 the maximum contribution amount is $5,000 for individuals under 50 years of age and $6,000 for those over 50. If you are under 50 and contribute $2,000 to your Roth IRA then you can only contribute $3,000 to your Traditional IRA. For a traditional IRA, you no longer can contribute after the age of 70 1/2 (RMD checks in). For Roth, you can contribute forever since no RMD are taken from this type of IRA account.
