Welcome to the world of learning to fly in Scotland ! Inverness is a
great part of the world, plenty of really interesting places to fly over and lots of flat ground to land in ! Be prepared to set off for lessons then have the weather cancel it, don't be put off you have plenty of time, you'll get a pilots handbook for your aircraft off of the internet as a PDF
All the advice you've had is good about not rushing to buy, the headsets you're using will do fine for now, it'll be a while before you're doing nav so don't buy the whizwheel, ruler, etc.
just be prepared for it to take a while - it took me 3 years flying out of OBAN and I passed four weeks ago. Keep at it, you'll love it !
cheers
Ian
