Deductions for independent contractor

I have been employed by a bank as an independent contractor and will make 120k this year

I drive one mile to station, park in parking station (have annual pass) and catch a train to the location.. is any or all of that deductible

 

Is my lunch a deduction..

Probably will be able to contribute around 48 k to a SEP 401k this year

 

I get family healthcare under cobra , i have a family plan, which is 36k per year, can i deduct the whole 36k or only the amount that would have covered me, or myself and wife..

 

Any other deductions which might be relevant, do not use home, but buy newspapers for reading for job.. dry cleaning ?

Thank you
