Your employer is required to withhold payroll taxes based on the W-4 you fill out and sign indicating how many allowances you are claiming plus any additional dollar amount you want withheld or whether your are exempt from income tax withholding. You may complete a new W-4 any time your tax situation changes and you need to change your income tax withholdings. Once you submit the new W-4 to your employer, it should not take more than 1 payroll cycle for the employer to begin using the new allowances. You may also want to prepare a separate W-4-equivalent for your state if you are subject to state tax. For example, California's W-4-equivalent is Form DE 4. Your employer should not change your federal income tax withholding allowances without written notification from you (or the IRS, which is rare) to do so.

If the incorrect withholding is for 2007, it is on your W2 and will be rebated when you file your income tax return.
No US employer can ever compel you to work for free. ALL work, without exception, must be paid. The employer can change your schedule, but must pay for your work.
As long as the employer properly applies federal wage rules to deciding whether you are overtime eligible, it can change you from salaried to hourly. The employer can reduce your pay rate, but you need not stay. Quit without giving notice.
A w-2 form tells your employer what percentage of your income you want withheld for income taxes. You can send them a "corrected" or change form anytime, but it will usually not take effect for one or two pay periods. Sometimes, when a bonus is expected, people will change their withholding to get a higher amount, and then change back.
