Which investing programs should be avoided? What do people think about Sharebuilder?

I’m 34 and want to start a Roth IRA for myself and plan to to contribute the max amount in one contribution each year. I know I want to go with either Fidelity, Vanguard, or T. Rowe. I know very little about investing and would like to feel secure with the investment. I know there are too many funds to choose from and I don’t understand them. Thanks for your suggestions.
