How to get into ski touring is a common question...
IMHO there are 2 stages.
1) Go hillwalking in the summer. Learn to navigate / pack / plan for a day on the hills
2) Learn to ski variable snow. Plenty opportunity to do this on piste in Scotland!
Kit has got much better in last decade. Lots of advice on web, no point repeating it.
Summary : pin bindings are much better option for touring.
Frame binding a good compromise if you want to use same ski for inbounds.
If you want to do an introduction course then I would recommend Blair Aitken.
He is BASI4 ski instructor and used to teach full time in alps before moving home to Scotland.
One of very few top level instructors running regular courses on Scottish snow.
Nice guy : and also a friend, so I am biased - but seriously he is excellent and his prices are great value.
His web site is below.
