Over the years we have run many brushless motors, the fastest motors used these days are 13.5T, and Craig is just as fast with a 17.5T as it has a better power delivery and others are moving up to a 17.5T. Any motor below 13.5T, while they have more speed and power, are much more difficult to drive around Cheadle.
To run a 13.5T motor then any ESC over 60A should do the job. The Hobbywing Xtreme Stock is pretty popular and quite a few are running Speed Passion Reventons. The Hobbyking ESC you linked to is a copy of a Hobbywing v2.1, which can use Hobbywing software which is useful as the Hobbyking ESC doesn't even come with a manual. You can pay a little more for UK supplied electrics, such as
this and
this, but they do have the advantage of UK backup and repair of anything goes wrong.
Batteries, you can use whatever capacity you want. Any capacity will last no problem, and anything over a 25C rating will do just fine with the motors we use. I would suggest the Turnigy saddles from Hobbyking, either the
5000mah/30C or the better spec
5100mah/60C. make sure you buy the lipos from the UK warehouse as there are restrictions on sending lipos by airmail. The rest you will probably have to buy separately from the international warehouse in Hong Kong.
For a charger I would usually recommend the
Core-RC UAC-50 due to its reliability and reputation, built it looks like Hobbyking is now also selling
their version of it. It has a 240v input, a lot of the cheap ones run off 12v and you need a separate 12v supply, which adds up to more than the Hobbyking charger I linked to.
