If none of these, then for the money you're probably better off with a combo like the 24-105 or 24-70 plus the 70-300L, but that said the 28-300 is still a decent lens, except for the barrel distortion at 28mm and the fact that it's fairly old (i've not heard any rumours of updates for this one, II might never come).
the 16-35 is a good lens, widest zoom canon makes, good choice if you can afford it.
tripod i'll presume you want more of a video tripod so i can't help you on that one...
