If the lager kit is using proper lager yeast, it should be fermented at low temperature, over quite some time. It will clear nicely by itself..
The bitter should have ale yast, so it wont clear that fast. Just tap it in the bottles as normal, and leave it for a while. The sediments should drop, and it will clear fine by it self.
But then again, why care about clearing beer. Haze doesn't effect the taste in a negative way, quite allot of people agrees that cloudy beer has more flavor. When you get into craft beer, you realize that all the greats has quite allot of haze, and a somewhat thick layer of sediments in the bottle. If you want to impress people by the way the beer looks, why not try to spend some time making a great bottle design (label, cap, real glass bottles instead of PET. etc...) ?
