As far as the IRS is concerned- moving expenses have to be Closely related in time. You can generally consider moving expenses incurred within 1 year from the date you first reported to work at the new location as closely related in time to the start of work. It is not necessary that you arrange to work before moving to a new location, as long as you actually go to work in that location. (extract from publication)
So if you actually worked in that location, you can support the moving deduction.
Also, job hunting expenses will be part of unreimbursed employee business deductions and they will benefit you only if you itemize and your total expenses are over 2% of your adjusted gross income.
You cannot deduct hotel and car rent expenses for you and your family while you are looking for a job in the same area. Since this would be your tax home. You are not temporarily travelling away from this place in search of job.
See extract below of the type of job search expenses that you can claim-
You can deduct certain expenses you have in looking for a new job in your present occupation, even if you do not get a new job. You cannot deduct these expenses if:
You are looking for a job in a new occupation,
There was a substantial break between the ending of your last job and your looking for a new one, or
You are looking for a job for the first time.
Employment and outplacement agency fees. You can deduct employment and outplacement agency fees you pay in looking for a new job in your present occupation.
Employer pays you back. If, in a later year, your employer pays you back for employment agency fees, you must include the amount you receive in your gross income up to the amount of your tax benefit in the earlier year. See Recoveries in Publication 525.
Employer pays the employment agency. If your employer pays the fees directly to the employment agency and you are not responsible for them, you do not include them in your gross income.
Résumé. You can deduct amounts you spend for preparing and mailing copies of a résumé to prospective employers if you are looking for a new job in your present occupation.
Travel and transportation expenses. If you travel to an area and, while there, you look for a new job in your present occupation, you may be able to deduct travel expenses to and from the area. You can deduct the travel expenses if the trip is primarily to look for a new job. The amount of time you spend on personal activity compared to the amount of time you spend in looking for work is important in determining whether the trip is primarily personal or is primarily to look for a new job.
Even if you cannot deduct the travel expenses to and from an area, you can deduct the expenses of looking for a new job in your present occupation while in the area.
You can choose to use the standard mileage rate to figure your car expenses. The rate for business use of a vehicle for 2007 is 48½ cents per mile.
