String Gauge/Action questions

[zeppelinfreak]

First question.

If I switch from 105-45 to 105-50, I wont really have to make any adjustments to my action, correct?

And what is typically the size allen wrench used to adjust saddles and the truss rod? If you need specs, Im playing a Fernandes Gravity Delux

Not a good assumption to make. You'll just have to string them up and measure your action to see if it has changed.
