Buying dirt cheap copies of the game from china etc and chucking the actual game away
BIG LETTERS
Utter tosh.
So if I get a LFD steam key. Could I DL LFd through steam?
If it's utter tosh then UK law SUCKS tbh.
The whole point with software is that you pay for a license/key, and not for the data.
It is not, under the law you are perfectly within your rights to download software which you already legally own - and since you own the cd key you own the software.
Case in point, all the people that have been sued for downloading music. Why didn't they just go out and buy the CD once they'd been caught and play this defense?
If this example were to be used, you would have to ask why somebody with that amount of money did not just buy the cd's in the first place. If they could afford to go out and buy them once the law got involved they would have likely been able to afford them beforehand.

If you buy it from Steam, yes. I know some games (i.e. Dark Messiah of Might and Magic) do allow you to buy retail and register with Steam, however some games do not.
Left4Dead i'm hazy with, however as its a Valve developed game it is likely you will be able to register it with Steam and download the client through the service.
Edit:
This should answer your question.
You're legally permitted to keep copies of original software media that you've purchased
You're legally permitted to keep copies of original software media that you've purchased, so as long as your downloading that same product and not sharing it, I don't see the problem. Of course you still have to be able to prove that you've purchased it in the past and have a license for it.
Got a source as proof for this? I was under the impression that this was a myth.
Copyright does not prohibit all copying or replication. In the United States, the fair use doctrine, codified by the Copyright Act of 1976 as 17 U.S.C. § 107, permits some copying and distribution without permission of the copyright holder or payment to same. The statute does not clearly define fair use, but instead gives four non-exclusive factors to consider in a fair use analysis. Those factors are:
the purpose and character of the use;
the nature of the copyrighted work;
the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
the effect of the use upon the potential market for or value of the copyrighted work.[22]
In the United Kingdom and many other Commonwealth countries, a similar notion of fair dealing was established by the courts or through legislation.
Afaik - as long as you have purchased your license, i.e. bought a key, then you can download the game from whereever/however many times you wish, it's not as if you haven't paid for your LICENSE.
But since 99% of games and DVDs have DRM, this is a moot point surely, since it's illegal to circumvent copy protection.
