Hello Rich, welcome to TSR. We're a helpful bunch around here, especially Pigcat (though he can be a bit humourless - nothing diverts him from the serious matter in hand).
My recommendations: a stick of Palmolive soap (about 50p from a supermarket) and a brush of some sort - see elsewhere for advice on that, but don't spend too much at the outset. Then a pause whilst you settle in here, learn to make lather, and have a look at the Buy Sell Trade board. Pretty soon a nice razor will catch your eye, and it will be time to get a sample pack of blades.
Six months after that, you'll be looking for a bigger bathroom cabinet.
