I currently have both B2 (visitor) and F1 (student) US visas.
I entered the using my B2 visa to join my family for vacation.
I will become eligible to stay on my F1 visa as soon as my family leaves.
How do I change my visa status without going back home?
Do I have to cross the border and re-enter?
If so, will I be able to cross the Mexican border and re-enter without having a Mexican visa?
Your facts are confusing. On one hand you state you have two visas, B2 and F1, and on the other hand you want to change your status to F-1. if you entered the country on visitor visa, you can file for change of status while you are in the U.S. providing you qualify for such status.

There are some facts missing as to why you 'really' used the B-2 ... I suspect it is because you were arriving too early to able to use the F-1.
Yes, you can file a change of status to F-1. But, YOU CAN NOT START SCHOOL until after it is approved.
The fastest way is to cross the border.
I can not comment on your ability to enter Canada, nor Mexico, without one of their visas ... this is a US Immigration Law blog.
