2,000 feet won't do your licence prospects much good!
Descend to 1,400 feet by Bough Beech (lake) and make your inbound call from there. Keep the railway to the left and you'll be outside the Gatwick zone.
Depending on runway in use, ATC will either tell you to report at South Godstone station, which is a bit hard to spot if you don't know it, but watch your GPS and stay with the railway - it's 4 miles straight in to 26, or you'll need to do a 30° or so to the right and report at Godstone, after which you head 260° and you'll be downwind for 08.
ATC are good, there's nothing to it. Just give them a call before you set off, sensible anyway in case Redhill is mud, tell them it's your first visit and ask for your hand to be held.
Don't forget to visit hangar 9 for tea and cake.
