Hi Ezza
I suggest you grab how to brew by John Palmer, it covers basic brewing through to all grain. If you get hooked on it brewing you will end up an AG brewer

Also have a look at the ABH website (link is below)
A couple of suggestions for you, don't use the yeast with the can, shell out 4 or 5 bucks and grab some US05 or BRY 97. You need good yeast and the yeast profile is a big part of the beers flavor, also a good healthy yeast reduces the risk of infection.
Leave the beer on the yeast cake for at least a week post ferment. There is a secondary process after fermentation, this will clean the beer up and if you take if off the cake the brew wont get the chance to do this.
Clean, Clean, Clean
And temp control is important.
Most of all just have fun with it, when you make a good one share it with a few mates, when you make a bad one tell ya mates it's their shout!
