If you are a W-2 employee, all miscellaneous itemized deductions subject to the 2% rule have been eliminated.
The rules and web sites you link to all apply to Employers -- the costs Employers can deduct. If you are self-employed and have a schedule C, you are an "Employer" (of yourself) and can deduct these expenses on your schedule C.
If you are an employee, they are not deductible.
But feel free to ask around until you find an accountant who will agree with you.
