with regard to headsets , have a good look on ebay , you can get some excellent david clark ones far cheaper than from a shop sometimes over 50%. I bought a second headset when i got my licence for pax as the flying school wouldnt let me borrow one , it wasa from a company in hong kong and cost 50 quid , not the best in the wolrd but it is comfortable and does a great job, in fact on short flights I prefer it to my DC . Rememeber when buying one they seem fine in the shop but think about what they will feel like after a 2 hr cross country . if they are tight on your head after ten minutes inthe shop it will be a nightmare after an hour or two .Think of human perfromance , if your head hurts or is uncomfortable then you will underperform and thats not good . They can be an expensive purcahse so make it the right one . Try borrowing one if you can and flying with it make a decision based on experience rather than whats seems right . I made my mistake with my DC I dont like it and its uncomfortable but it cost 350 quid , mail order ( not reccoemmended unless you know the headset your gonna buy is comfortable )
Thats my thoughts anyway
