Please don't get a bodylift, they just aren't right.
As for the small lift, we put 2 inch aluminum blocks on my friend's suspension springs on his yukon and it rides smoother and is taller. I would get blocks for now, they are cheaper and give you an idea of what the truck will look like with a real suspension lit. Its your call, but there's a start.
