Replying from a UK perspective:
1. You should take lunch
2. My personal view is if you're clocking up that much overtime so regularly then there is too much work for one person and you need an assistant
3. I would approach the paying for the other half of tuition by pointing out that your entire package doesn't include overtime or any other financial benefit, and them paying for that would be viewed by you as a financial benefit (though does this affect your tax?)
4. Christmas - maybe your boss is simply a non-Christmas person and doesn't 'do' gifts.
5. If people on a lower or similar level to you have a bonus and food/car allowance built into their package, you need to do some serious negotiating to build up your own package!
Don't mention the Christmas gift at your review, but do cover the issue of overtime/bonus/allowances that others are getting.
Good luck and let us know how you get on.
