with it being education.... you don't want exactly expensive gear anyway cause let's face it, the kids will still abuse it and have accidents.
I say squier for the guitars, vintage modified series are a big plus for me too (although i can only play them upside down cause they don't make lefties on that range) the HSS is a good idea as well.
in terms of amps, I don't quite know what to say. modellers are alright for the classroom situation but the problem you have is it is best to keep it simple for the students which can be a pain the rear if you have about 2 million knobs.... also with modelling amps, the kids can be distracted, ''ooh what does this button do'' syndrome starts taking over. so either go for about 50-100W solid state twin channel amps with say a reverb setting or go for slightly more expensive but smaller wattage (but just as loud!) tubes amps such as the HT-5.
the problem then with the tube amps is being sensible cause if you flick the on and standby switches together you could screw up the tubes.
but anyway, squiers are your best bet.
