You can be laid off during family leave so long as the lay off can be shown to be bona fide not related to your leave or personal situation--for example, if it is a general layoff of everyone your department or location or company, as you indicate it is. Family leave protects you from losing your job because you are taking leave, but not due to factors outside that leave--for example, it does not require the employer to keep your location or department open just for you. Disability payments will likely stop once your employment ceases, since if you are not working anyway, you are not entitled to income replacement for an inability to work due to a medical, etc. condition. Similarly, the employer's oblligation to pay any insurance premiums will end once your job ends, though you can then continue to purchase the same insurance at your own cost through COBRA.
