Congrats Ben!
As for what to do, I'd suggest taking it slowly but steadily. You certainly don't want to rush into doing 200 mile cross-country - but on the other hand, you don't want to be stuck in the local practice area for the next 6 months because you're too scared to go out.
So, what I'd suggest is this: for your first flight, stay in the circuit. For your next couple of flights, go to the local area. Then, do a land-away at a field you know. Then, a land-away at a field you don't know. (All subject to weather, of course - if you book a plane for a cross-country but the weather's only good enough to do circuits, you're allowed to change your plan!)
I wouldn't rush to get your license from Gatwick. Do a few flights by yourself first. And, by the time your license arrives, you should be just about comfortable enough to take your first passenger - just out to the local area.
But the most important thing is to have fun!
