Are you starting a few different IRAs or combining a few different accounts into one IRA? If your just starting retirement, I would check out Vanguard's Target Date funds. They are easy to start investing, low minimum start amounts of about 3K, and feature very low cost funds compared to other funds. Once you build it up then you could stay in the fund if you like it or split up the funds into other investments. Watch out for loaded funds. Many will have front, back, both, and other fees with them. This will eat into your returns. You can make contributions into your new Roth IRA up to $5,000 till April 15th, then $5,000 for 2009 tax year. Even if you have more then 1 Roth IRA the limits are the same combined, so you could not have 2 or more and contribute more then 5K per tax year.

I have different accounts with different banks. I plan on starting IRA's with at least two different banks

Why do you want more then one Roth IRA? Also, you might look into fees at the banks. A brick and mortar bank will have additional fees for the same funds you could get direct. I would suggest looking into a discount broker firm online such as Vanguard and Fidelity, among others.
