Onway,
If your husband is still on Revenue's records as being self-employed then he should submit a return for 2009 showing his income as nil and including your pay and tax details. Make sure to include your ppsn if you have not previously been jointly assessed.
Assuming you were married prior to 2009 then you can indeed use his credits but as I said paye will not/cannot deal with a person who is registered as self-employed. He will presumable need to deregister by contacting registration section.
