The theory exams have changed significantly since 2010, some text books will be very out of date.
There have been a lot of changes as we transition to EASA regulation, air law and operational procedures probably more than the rest. I'd definitely get the latest book for those. The other text books are probably okay, but get up to date exam revision material for everything, whether that's books or online.
If you want to do the LAPL, but your school doesn't know much about it, I'd say that's pretty poor and go find another training establishment that does. However, I agree with XA, go for a LAPL medical, then get a NPPL with SSEA class rating, which you can then use to apply for a LAPL.
