I have never heard of anyone pre-ordering main courses in PE, but that doesn't mean it isn't possible. You can pre-order specialist dietary meals -

Before take off, or just after, menus are given out. There is usually a variation on the beef / chicken / veggie options- you could mention then if you want a particular dish.
I believe they just serve from the front, but stand to be corrected on that, as I don't really pay attention.
I don't drink wine, but they always seem to have plenty of options.
I am have no idea what ½ TUS means. either I am afraid.
For the past few years I have found PE food okay, but not spectacular- it is nice to have proper cutlery andy glasses but, as with a lot of things with VS these days, there is an element of style over substance. A lot of money spent on packaging (despite their claimed geeen credentials) and not to much on the actual food; but that is more in economy.
I haven't flown BA for years, so can't compare their offerings.
