Profit Extraction

Hi All

We have a contractor company,turnover 100,000 , i am doing tax planning and need help on following issues,

1-How much pension contribution can be made and will it be allowable against trading profit?

2-Client husband is on full time employment,earning 30K, can he  only be director as he help little bit to client to get work and can company contribute for his pension contribution and how much?

3-what other option to use husband to save some tax as it seems we can only vote him little bit dividend as he already earning £30K so he donot have to pay any other tax on personal side,

Any other tax planning advise,

Thanks in advance
