Wisdom teeth before veneers
It is absolutely impossible to make any evaluation of your wisdom teeth without viewing xrays and performing a clinical examination. If your wisdom teeth are symptomatic (hurting or swollen) then they should probably be taken care of prior to porcelain veneers.

Not necessary for veneers, but you need orthodontic therapy instead of veneers
You have very pretty teeth that simply need to be moved into their proper position. The teeth could be expanded to broaden your smile while straightening them with Invisalign or traditional orthodontics. I am a cosmetic dentist who has performed thousands of veneers. I also have treated hundreds of Invisalign cases and orthodontics will be a more conservative, non-destructive treatment for you to have done to treat your condition.
Wisdom teeth don't factor in porcelain veneer planning
while you certainly would benefit from the removal of your wisdom teeth, it isn't a factor to be considered when planning a porcelain veneer case.
