I am trying to see if its possible to file tax together for W2 + Business (Sole P - Single owner)

I am trying to see if its possible to file tax together for W2 + Business (Sole P - Single owner)  :

Details:

    Tax year 2022, Permanent resident, State : California
    I and spouse(Married filing jointly)  will get W2's for 2022, say for total X amount.
    I have EIN and Sole Proprietorship business, which started this year in 2022 

    For 100% business use i brought two vehicles in 2022 (GVWR > 6K lbs) and 1 sedan car (< 6k lbs) 
    For personnel use i have another suv, apart from above.
    I have very less business income this year as i recently started it, (say business income for 2022 =  Y)


I am trying to use full bonus deprecation on the two business vehicles i brought this year, and up-to 18K(max allowed limit, i believe) for the car as all three vehicles are for business use only.

My questions :

    Would i be able to combine the W2 and Business income i.e. X+Y in same filing, and use the 179+bonus 100% deduction on business vehicles for federal filing, would it help to reduce total AGI with 100% full bonus deduction for business vehicles?
    I am in California, looks like state only allows up to $25K deduction in year 1 on business vehicles, is it per vehicle or total ?
    what forms would be needed to use while filing, can your firm can file for me ? 

    Anything else i need to be aware of on the rules/requirements related to above scenario, if you can share links would be helpful

Appreciate your help and suggestions !
