I noticed a HUGE difference in clarity once I started using whirlfloc, as in no more chill haze at all!
A couple of easy things you can do to increase the clarity is making sure you have a good hot break and a good cold break. Using whirlfloc, along with those good hot/cold breaks means that giant gobs of protein fall out readily, and you end up with a nice clear wort and nice clear beer in the end.
Another thing is to use more flocculant yeast. S04 will clear the beer well and form a tightly compacted yeast cake, as will nottingham. Some yeast strains don't flocculate as well and so don't result in a bright beer without cold crashing.
I don't do anything else- not filter, or cold crash (although with S05, sometimes I've had to!).
