Thanks for the tips, folks!
I can't really remove the roof rails, as I do occasionally throw something on top. Same with lowering - I don't go off road as often as I'd like, but I do need the clearance.
With the upper grille, I guess I could partly block it off. But I'm hesitant to do it as in summer it gets up towards 45C (113F).
Besides that, I haven't had the time to do anything lately.
