Roth IRA and Tax Considerations, Other Concerns

[Jeffage]

I planned to max my Roth this year (and every year in the foreseeable future). Is the income cap on a Roth 100k? What happens if you do one and then end up making more than that by the end of the year...would that money have to be withdrawn, would their be a penalty, etc?

What's the alternative? Regular IRA? Right now I put 300 a paycheck into my work's 401k program. Should I max that (they don't match). Should I just let my Merryl Lynch guy do this stuff or handle it through my bank? Other info...I don't own a home yet (this is my last year of renting) and am 25.

Thanks,
Jeff
