You shouldn't need to transfer to the bottling bucket the night before, if there is stuff still churning around and up in solution, the beer needs to sit longer.
For your bottles, cleaning them well first will help ensure that your sanitizer is able to do its job. Clean them, rinse them then you can go ahead and sanitize, no need to dry between cleaning and sanitizing if you rinse first.
For bottling conditioning, 85 is definitely on the warm side. You typically want to bottle condition at a more moderate temp, say around 70ish. I can't say from personal experience that 85 is going to be a problem for bottle conditioning, but definitely hotter than I'd like to keep them. Once they are carbed, most brewers will move the beer to a cooler spot and store the beer at 'cellar' temperatures (55 ish). Doesn't sound like that will be possible for you though... perhaps you need to dig yourself a fermentation cave! Hotter storage temps can speed up any staling reactions that might occur, I think your best bet in general is going to be be to drink your beer fairly quickly... let it carbonate, then put a bunch in the fridge.
