What does this mean? i got this from my IRA account from WAMU...?

It means that your IRA is not insured by the FDIC (Federal Deposit Insurance Corporation) so that if WAMU fails in it's fiduciary responsibility to care for your invested funds properly, your redress will be through the SIPC which is the Securities Investor Protection Corporation. You might want to check to see how they stand for insurance coverage. This is ALL uncharted territory and we don't know upon whom (which companies) we can rely and which we can't. Probably there will be no problem for you but that advice is worth exactly what you've paid for it.
