You could always make a hotbutton to function as you described (for the most part anyways, some mobs this would be no good for.)
By making a new hotbutton in the Actions window, putting "/target a" in the first line, then "/loot" in the second. If lag causes this to not function well you could always put a small pause command in the second line and move the loot one to the third. (its honestly been months and months since I set up a pause command but i think it just uses "/pause #")
No real way of seeing your partys buffs without asking.
Likewise with spells, although using multiple chat windows you could filter spell information that is important to you to its own window so you could easily see it all without being lost in other battle/chat spam.
Seeing mob hp as numbers? I have no clue there. As far as your own that is displayed, custom UIs seem to offer a wide array of customization on things like that and I've seen many that offer a heads up display of your own HP without having to open your inventory to see. Heck, for all I know the things I mentioned as not possible above are possible with different UIs, I've never used anything but the EQ defaults.
Befallen high level? Unless it used to be extremely low level it should be the same Befallen you remember.
