My question involves unemployment benefits for the state of: California

I was a salaried employee (regional sales mgr.) for a company for 2 years before business slowed at which time the employer decided to make me 100% commission based (still regional sales mgr.). However, the only aspects of the job that changed were the salary to commission structure and the W2 to 1099 change. The employer continued to provide a desk, telephone and laptop for my use (although I wasn't in the office on a daily basis). They reimbursed travel expenses when I called on clients and paid for expenses to attend trade shows. I attended weekly meetings at the facility and was provided with a company car the last six months of my employment. I was also included on the company health insurance plan but reimbursed them for this. Lastly, I was not permitted to represent any other companies. When I made the attempt, I was fired.

Does it appear I was treated as an employee or contractor? If it seems I was improperly classified, how do I go about challenging EDD of California that I qualify for unemployment? Does this open up a big can of worms with my former employer? Thanks.
