Since your kit is a Youngs Pilsner kit which comes in at only 1.5kg of liquid malt my advice, unless you have bought the ingredients already, is to substitute 500g of the brewing sugar which the kit recommends with 500g of light or extra light spray malt (alias DME). Brewing short i.e to less volume say 20 litres will also help to improve the flavours but if you do that reduce the sugar slightly, say 200g, to allow for this, but do not reduce any malt. And unless the kit instructons tell you to ferment at low temperatures, ferment at room temperature i.e around 18-21*c. This is because the kit is likely to be supplied with an ale yeast which needs a higher temperature to function rather than a lager yeast which works at lower temperatures. Either way follow the kit instructions.
Finally don't try to rush it. You should aim initially at 2 weeks in the fermenter, 2 weeks to carbonate the beer in a warm place, and then 2 weeks to condition and mature in a cold place before you try your first one. When your technique improves you will be able to adjust these timings to suit.
Best of luck with it.
