That's actually a standard Jazzmaster feature. It's a floating bridge.
I didn't know which position the bridge had to be or which height it had to be.
So I watched some videos and adjusted it, but the problem is, it doesn't feel right.
There is buzzing still, the high E and B string touches the frets when I am playing around the 12th fret.
Then it's not adjusted properly.
Your best bet is to take it to a tech and get a proper setup. This is good advice for any guitar, really, but Jazzmasters are more finicky than most. If you don't have a guitar tech near you, you can learn how to do a setup yourself: http://www.webrocker.de/jaguar/2007/05/12/setup-for-jaguar-and-jazzmaster/
String and pickup heights are listed there (they should be basically the same even for the Stratomaster), but don't just skip ahead - you won't get anywhere unless you check/set everything.
Additionally, when I try to play the high E string, it tends to 'fall off' the fret board, is it just me playing badly or is that another issue?
Could be either, to be honest. Look at your neck visually - is the high E much closer to the edge of the neck at the base of it than the low E is? If so, then you need to loosen the bolts on the back of the neck and straighten it (push the head end towards the low E side). But if not, then it's just your playing. Some guitars have relatively fat fretboards; the Jazzmaster has a thin one.
I don't want to change the bridge, as I want to keep the guitar as "Mami's guitar"
The good news/bad news is that Mami doesn't have this bridge on her guitar. She has an Adjust-O-Matic.
