Maybe pick up a extra high e and b string while your there.
If the Squier is the same guitar you had years ago, you might want to have it checked out first.
I just put on a set of D'Addario on my electric/acoustic and I am happy with them so far..
I also put a string on my Fender no knowing the guage or manufacture... I used D'Addario now and I've noticed no difference in the feel or sound.
